Predictive Maintenance Technology Conference & Expo
September 11-13, 2007
Las Vegas NV

Workshop #3
Electrical Predictive Maintenance Basics

Part 1 Electrical Inspection using Infrared Thermography by John Snell

Part 2 Electrical Inspection using Airborne Ultrasound by Jim Hall

Reliability managers and technicians should attend this one day course to learn more about electrical applications for infrared thermography and ultrasonic detection. Whether you already own equipment, are “shopping around,” deciding to add the technology or just want to find out more, spending a day to learn about infrared and ultrasound will pay large returns.

Some of the topics John Snell and Jim Hall will discuss include:

• Motor control centers, panels, and components
• Exterior substations and components
• Distribution and transmission systems
• Transformers, circuit breakers, and buswork
• Infrared inspection windows
• Ultrasonic inspection ports

The workbooks for this course consists of the presentation slides (in color) and several useful background articles.

The only conference with a 100% Satisfaction Guarantee or your money back!

When one is considering whether what they are doing is really Root Cause Analysis (RCA) or not, ask yourself if you are expensing data collection efforts (evidence) for the sake of time?

If you are pressured into providing quick conclusions, this usually means that you will not be permitted to collect the necessary evidence to prove that what you say is correct or not.

Traditional Quality tools such as “5-Whys” and “Fishbone Diagrams” are often attractive to managements because they are timely and inexpensive. However, when pressured for quick results, they often are not “accurate”!

After tightening a hose clamp you have the band sticking out. This is very dangerous and can cause very deep cuts. Cut a piece of rubber tubing the length of the band. Squeeze it flat and slide it over the band.

This will protect arms and hands when reaching into tight areas where there are many clamps.(Rotary Liquid fillers)

When adding failure modes to the FMEA part of an RCM study ensure that the failure mode is the physical cause of the loss of function. After all it is the physical failure mode behaviour that we seek to change when deciding what maintenance to do.

So for the failure modes associated with no flow:-
- don’t say pump stopped, say broken shaft or seized bearing, or collapsed impellor or similar. In other words if you can relate the physical mode of failure to the loss of function, maintenance technicians will know exactly what happened and the maintenance task can be quite specific.

Building an effective FMEA provides an excellent troubleshooting guide for both operators and maintainers, and a side benefit is that it can be used to build reporting codes in work order management systems.

Vibration Analysis (Statistical Analysis) Tip

Statistics – the science of collecting and interpreting numerical data (Webster Dictionary – Third Edition)

Analysis – the separation of a complex material or concept into its elements (Webster Dictionary – Third Edition)

By putting these two elements together “Statistical Analysis”, you come up with a very powerful tool that can be used to aid you with your day to day vibration analysis duties. Specific techniques can range from setting meaningful vibration alarms for equipment in existing condition monitoring programs, determining which similar machines in a one-time vibration survey are the outliers and need more in-depth analysis, detailing the variances in vibration signals from point to point in a given machine or system, or aiding companies with “identical” machine types at various locations to set real world target vibration amplitude levels or standards.

How can you deploy these techniques in your programs? There are software packages available that will run various routines on defined data sets and many of the most popular Vibration Analysis / Condition Monitoring Systems offer additional software packages just for this purpose. Another way to perform these routines would be to develop custom worksheets that give the user total control over the process of performing all mathematical routines on the data being studied.

This last choice (building custom worksheets) is one of the more time consuming ways to perform Statistical Analysis on vibration data, but has proven to be one of the most reliable / beneficial methods available. Many software providers do not give the user total control over the applications of the mathematical formulas used to perform these studies. Additionally, the most common Vibration Analysis / Condition Monitoring Systems’ software packages are typically linked to the vibration database in such a way that any “Bad Data”, overlooked baselines, or known mechanical faults will create “FALSE” results in the end calculations. By having “TOTAL” control over which machine data sets you use to for analysis, what tolerances or targets you set for your outliers, and how you run your mathematical routines, a wealth of knowledge about your plant’s rotating equipment can be uncovered.

DC Motor Maintenance Tech Tip

On occasion, repair and maintenance companies will use silicone lead wire or silicone sealant on motor openings in dirty environments. When these items are used with DC electric motors or generators, the silicone vapor, regardless of the amount, will cause rapid wear of brushes and the commutator bars. The carbon and copper dust will permeate the motor armature causing a premature ground or failure.

When having a DC motor repaired, ensure that you specify that no silicone components are to be used.
