SEL arc flash detectionMinimize Dangerous Arc-Fault Energy

Schweitzer Engineering Laboratories’ new arc-flash detection (AFD) relay provides fully automatic protection against arc-flash events. The SEL-751A Feeder Protection Relay uses fiber-optic, arc-flash light sensors to detect the light created by an arc-flash event. To prevent false tripping, the SEL-751A looks for an overcurrent that coincides with the light flash. When both conditions are met, the AFD solution sends a trip signal to the circuit breaker in as fast as 2 ms. This fast tripping significantly reducing the damage-causing energy released by the arc-flash event.

Tracing Fan Vibration to Flexible Soil

In this case, the cause of machinery health problems really did start from the ground up.

The call came in to Mechanical Solutions, Inc. (MSI) from an electric power gen company. Excessive vibration was plaguing two newly installed Induced Draft (ID) fans at one of the company’s flagship generating stations. The two units, each driven by an electric induction motor rated well in excess of 5000 HP, were operated in parallel at a constant speed with dampers that controlled the downstream flow of air. Elevated ID fan vibration levels at one times (1x) the running speed had been reported by the station. In fact, this vibration had been substantial enough to exceed the fan trip levels during startups time and again. Unfortunately, traditional vibration analysis techniques had not been successful in helping to resolve what initially appeared to be a straightforward machinery unbalance and/or misalignment problem.

To get to the bottom of the fan vibration issue, MSI performed a combination of operating forced response testing and impact modal testing. The purpose was to collect vibration data at locations throughout the fan systems, including the fan bearing housings, bearing supports, bearing sole plates, concrete pedestals and concrete floor pads.

The impact modal testing was conducted—safely—while the ID fans were running, so as to determine the natural frequencies and the mode shapes while the bearings were energized— which accounted for the important sleeve bearing stiffnesses of the units. An instrumented impact hammer was used to excite each bearing housing in the axial, vertical and horizontal directions, while a set of accelerometers and two multiple-channel spectrum analyzers recorded the response data throughout each fan system. The amount of force put on the fan bearings, supports and foundations at each frequency was transmitted by the piezoelectric crystal contained within the head of the impulse hammer. This input force was divided into each of the acceleration responses to determine a frequency response function (FRF) between the locations/directions of the hammer impacts and the locations/directions of the responses at the accelerometers. The logarithm of each FRF was plotted versus the frequency—which allowed both the low and the high response modes to be inspected with equal clarity. The peaks in the FRF plots represented the natural frequencies of the fan-pedestal-floor structural systems. The impact modal testing also was used to determine the mode shapes of the fan systems at each natural frequency of vibration. Data for each of the impact modal tests was acquired at approximately 50 locations in the three orthogonal directions on the bearing housings, bearing supports, bearing sole plates, concrete pedestals and concrete floor pads.


A specialized operating forced response vibration technique also was utilized to record test data in three orthogonal directions throughout the fan systems. This allowed the data to be subsequently processed to produce detailed, animated operating deflection shapes (ODS) of the fan systems. The data was collected under maximum load conditions, where the maximum forced response was present in the fans. Each mode shape and ODS animation displayed the relative motion, i.e. the amplitude and the phase, at each measurement location on the structure at a selected frequency. The animations were beneficial because they illustrated the relative motions of the various system components in an exaggerated fashion, which encouraged the efficient identification of the root cause(s) of the vibration problem. Still images from the ODS animations for the two ID fans are presented in fig. 1.

The collected test data confirmed both of the ID fans had excessive vibration amplitudes that occurred in the horizontal direction at the locations of the outboard bearing housings and outboard support pedestals. The vibration spectra showed several harmonics of the fan running speed, and the highest peaks occurred at 1x and 2x the running speed. The ODS test results displayed horizontal rocking motions of the inboard and the outboard pedestals in both of the ID fan installations (see fig. 1). There also was clear evidence of looseness of the bearing assemblies in both of the fans (e.g. the housing, support and soleplate, especially in the outboard bearing assemblies).

The ODS data for ID Fan A showed in-phase horizontal rocking motion that was driven by the rotor motion at both the inboard and outboard support pedestals. flexibility of the base mat or soil underneath the pedestals allowed the pedestals to develop this side-to-side rigid body motion.

The test data for ID Fan B illustrated a more pronounced rigid body side-to-side or “rocking” motion at the outboard bearing pedestal, because of 1x running speed excitation driven by the fan’s rotor. Again, flexibility of the base underneath the pedestals allowed this horizontal motion to occur. ID Fan B’s rotor also described a relatively large horizontal orbit in the outboard bearing due to the motion of the bearing housing. Though the relative displacement of the shaft in the outboard bearing was relatively small and within operating specifications, the absolute motion relative to ground was several times greater. ID Fan B showed approximately 20% more deflection at the outboard pedestal in the horizontal direction than did ID Fan A, and 50% less deflection at the inboard pedestal in the same direction. Based on this information, MSI concluded that the rotor critical speed had shifted downward toward the running speed due to the high flexibility of the outboard support pedestal. This shift caused the fan to operate at resonance with the running speed.

Further, an independent structural natural frequency of the outboard pedestal was identified near the running speed. The rotor critical speed and the structural resonance interacted with each other, and were the likely cause of the modulated orbits of ID Fan B’s rotor. Rotordynamic analysis showed that the lateral stiffening of the outboard pedestals would detune the 1x resonance sufficiently to decrease the amplitude of the vibration responses to acceptable levels.

Ultimately, the root cause of the excessive vibration was the flexibility of the soil that was beneath the base mats of the supporting pedestals of each ID fan. It was recommended that the horizontal stiffness of the outboard bearing pedestal and support assemblies—e.g. the base mats and the underlying soil—be increased substantially. This modification would de-tune the offending resonance condition of the rotor critical speed and the pedestal structural natural frequency to create sufficient margin versus the fan running speed. In addition, it was suggested that all of the bearing housing and support assemblies be tightened and stiffened as much as practical to minimize the overall vibration of the fans. It was also noted that efforts to reduce the vibration levels by improving the balance or the alignment of the units beyond the manufacturer’s recommended parameters would at best provide a limited and temporary solution to the problem. Exceptional balance and alignment levels generally cannot be maintained in plant rotating machinery on a practical basis—especially in cases when the rotor is exposed to fly ash that will accumulate easily during the routine operation of the machine. The root cause of the vibration problem, soil flexibility, would have been extremely difficult and very costly to trace without the benefit of the specialized and well-proven troubleshooting approach that was implemented in this case. On the other hand, a design audit by a qualified firm—before the ID fans were installed at the facility—could have been exploited to avoid this puzzling vibration problem altogether.

My Take: Cash For Clunkers and Crush For Credit



Jane Alexander, Editor-In-Chief

Tuesday, April 7, as I thought I was putting the finishing touches on this column about some exciting motor news, I took a few minutes to scroll through the online edition of the New York Times. In the Opinion section, an editorial entitled “Cash for Clunkers”* caught my attention. Its focus was on a movement in Congress to help take gas-guzzling clunkers off the nation’s roads and replace them with more fuel-efficient models. According to the editorial writer(s), while this idea has benefits for both the environment and our troubled auto industry, there’s a right and wrong way to get it done.

MT News

News of people and events important to the maintenance and reliability community

Robert J. Pagano, Jr. has been appointed president of Industrial Process (IP), one of the ITT Corporation fluid businesses headquartered in Seneca Falls, NY. He replaces Ken Napolitano, who has been named president of ITT’s Residential and Commercial Water value center headquartered in Morton Grove, IL. Pagano is not unfamiliar with his newly announced role. He actually began his ITT career with IP, holding a series of increasingly responsible positions over the years. He eventually went on to lead that business as president from 2002-2004, a particularly challenging period, during which he helped position IP for future growth. Most recently, he had been serving as vice president of Finance for ITT Corporation, and had been CFO for the Motion and Flow Control group. ITT Industrial Process manufactures and markets industrial pumps, valves, monitoring and control systems, water treatment products and aftermarket services globally under the Goulds Pumps®, Fabri-Valve®, PumpSmart®, C’treat® and PRO Services® brands. It has 18 manufacturing plants, 14 service facilities and 32 sales offices worldwide with more than 2200 employees.

John Crane, a division of global technology business Smiths Group, has announced the purchase of Orion Corporation, a leading U.S.-based designer and manufacturer of hydrodynamic bearings for energy and general industrial markets. Headquartered in Grafton, WI, Orion complements and extends John Crane Bearing Technology, a business unit formed following the corporation’s 2007 acquisition of Sartorius Bearing Technology (SBT), based in Gottingen, Germany. Orion designs and manufactures hydrodynamic bearings for high-speed turbine, generator, compressor and gear-drive applications for the power gen, oil and gas and general industrial markets. Employing 270 people at its Wisconsin and Nebraska facilities, it reported sales of approximately $50 million for its 2008 fiscal year ending October 31.

On a related note, John Crane, already a leading supplier to the refining market, has recently added a new Production Solutions division to serve the upstream part of the oil and gas industry (oil and gas recovery, with respect to optimization of the well). Led by Tom Whipple, president, the Production Solutions division is currently made up of CDI Energy Services and Fiberod, two Texas-based companies. CDI is one of the largest artificial lift service companies in North America. Fiberod is a leader in innovative fiberglass sucker rod (FSR) technology.

Emerson has acquired epro GmbH (epro), a privately held Gronau, Germany-based company that engineers, manufactures and assembles API 670-compliant protection systems delivered to the process industries worldwide. The deal expands Emerson’s online machinery monitoring capability with a full API 670-compliant protection offering. It is also expected to speed availability of next generation solutions. Terms of the deal were not announced.

ExxonMobil recently inaugurated its newest high-efficiency cogeneration plant at its Antwerp refinery in Belgium.According to the company, this facility is more efficient than many traditional cogeneration plants because of its heat recovery system. In addition to generating steam, the cogeneration operation utilizes heat created in the gas-turbine exhaust to heat crude oil, the initial step in the process of converting crude oil into refined products. The unit will generate 125 megawatts and reduce Belgium’s carbon dioxide emissions by approximately 200,000 tons annually—the equivalent of removing about 90,000 cars from Europe’s roads.

“This new cogeneration plant allows for the efficient generation of electricity to run pumps, compressors and other equipment in our facilities, while at the same time, producing additional steam that is needed in processes that transform crude oil into refined products,” notes Gilbert Asselman, manager of the Antwerp refinery. “With the latest technology, cogeneration is significantly more efficient than traditional methods of producing steam and power separately. This results in lower operating costs and significantly less greenhouse gas emissions.”

With the launch of the Antwerp facility, ExxonMobil now has interests in about 4600 megawatts of cogeneration capacity in about 100 individual installations at more than 30 sites worldwide. New facilities under construction in Singapore and China will increase ExxonMobil’s cogeneration capacity to more than 5000 megawatts in the next three years.


The SMRP Board of Directors of the Society for Maintenance and Reliability Professionals (SMRP) has approved a program to develop programs, products and services in partnerships with its members. Known as the “Member Affinity/Partner Program,” it will allow supplier members to partner with SMRP to develop and implement programs, products and services to meet member needs. Supplier members that are interested in partnering with SMRP to provide a program, product or service to the industry or profession should submit a written proposal, including program features, benefits, cost conditions and the details to the Improve Member Services Committee. The Committee will screen the program against some very basic criteria, and, if necessary, the member will fund research among SMRP audiences to determine if there is interest in the program. The committee and staff will analyze research results and if a sufficient level of audience interest is evident, will present the proposed program to the Board of Directors. The first program of this type to be approved is with ABB Reliability Services to provide a series of workshops at no cost to SMRP members.

Viewpoint: Aligning The Right People For Profitability


Jeff Shiver, CMRP, CPMM, Managing Principal, People and Processes, Inc.

Studies have shown that many organizations suffer from a self-induced failure rate upwards of 70% in equipment reliability processes and practices. These failures result from sources such as operator error, management, purchasing and maintenance methods, to name a few. More rarely considered as a reason for failure is organizational alignment and structure—yet it can have significant financial and functional impact. This is especially true when Maintenance and Operations are decentralized and using high-performance team concepts with little or no direct supervision, and no real centralized support functions such as Planning and Scheduling.

While many manufacturing organizations abandoned the high-performance team concept over 15 years ago, not everyone followed suit. Some organizations in the last few years have chosen to revisit and pursue the concept with the great intent of empowering people down to the lowest levels. The few supervisors who remain in the organization become “coaches” since it is the team that now makes the decisions. Often, the reality is that the response time for making significant decisions slows greatly. Consider that one high-performing team organization worked with a consultant for over a year with weekly meetings just to determine (via a voting process) if they were going to plan and schedule maintenance activities.

Although there are advantages to the high-performance team concept, the disadvantages for the Maintenance group and—ultimately—for the organization as a whole, outweigh them. Consider the fact that teams don’t like to share ‘parts’ of people, especially craftspeople. Because craftspeople never work in other areas, they have no knowledge of ‘site’ or other area equipment. Because the ‘team lead’ responsibilities change every day or week, there is no continuity in direction other than getting product out the door. Loss of direct supervision skilled in maintenance is one of the first casualties. This is quickly followed by the loss of Maintenance Planning and Scheduling with the focus on production goals of the craftspeople. In light of no planned work and no preventive maintenance, equipment reliability suffers. Costs go up. Since we can’t use the craftspeople across different areas, we must staff shutdowns and other activities with contractors. Craftspeople living the cycle of reactive chaos become disenfranchised and leave the organization. As equipment reliability falls, so does the profitability due to increased downtime and ensuing loss of capacity.

Setting up the right organizational alignment to thrive and profit starts with educating leadership. A proactive team culture requires effective Maintenance Planning and Scheduling; knowledgeable and dedicated craftspeople that have direct supervision (ideally with craft skills); a Maintenance Engineering (not Project Engineering) function; and a partnership with other stakeholders such as Operations. When these functions are properly staffed and supported with mutually beneficial partnerships, you are well on the way to creating a winning team that balances empowerment with profitability.

As a long-time maintenance practitioner and now as managing principal of People and Processes, Inc., based in Yulee, FL, Jeff Shiver has educated and assisted hundreds of people and numerous organizations in implementing Best Practices for Maintenance and Operations. E-mail:

Lubrication Checkup: A First Step Toward Wellness

“We are a small manufacturing company with a maintenance staff of 8 persons. We currently support a loosely put together lubrication program, but continue to experience many premature bearing failures. We recognize the [lubrication] program is probably not very effective, and would like some suggestions on where to start our improvement efforts.”

Getting the most out of your lubrication program requires an understanding of lubrication fundamentals. Performing a “back to basics” examination of your current program will ensure that it is built on a solid foundation and deriving optimized benefits from effective lubrication.

Examining the following two “basic” areas will help you in determining if you have major problems with your lubrication program and give you a great starting point for improvement:

1. Cleanliness – The old adage “cleanliness is next to godliness” must be the mantra of the day when working with lubrication. Bearing surface areas and lubrication systems are NOT dirt tolerant. Poor work practices and dirty lubricant storage/handling tools and areas are responsible for many premature bearing failures. Develop a cleaning regimen as part of the PM task. Ensure the lubricant reservoirs and lubricant delivery devices are always kept scrupulously clean.

2. Over-lubrication – Most bearings and motors are actually “killed with kindness” by over-zealous maintainers over-lubricating bearings. Telltale signs include:

a. Blown seals – A seal is no match for the pressure of a grease gun in an untrained hand.

b. Oceans of grease surrounding or dripping from the bearing – “More is better” is a false assumption when it comes to lubrication.

c. Multiple non-standard grease guns still in use – No two grease guns are alike; they all have different pressure ratings and delivery speci? cations.

d. Subjective PMs stating “lubricate as necessary” – Rarely will two individuals’ ideas as to the necessary amount be the same.

e. Grease-packed motor armatures – Many motors expire prematurely from over-lubrication.

On your organization’s road to lube wellness, it’s important to examine for evidence of these signs. Then, seek help from a Lubrication Engineering specialist to provide proper training and assistance in realigning your lubrication program.
