Is the PLC included in your Electrical PM?

If so, what all items related to PLC are in your electrical PM plan. Please share with the rest of us. Thanks

Rob, I agree with the ROI issue but with some of the older gear and I mean 1930 to 1950 vintage it is not easy. Most of my applications are in utility power generating stations.
The OSHA aspects are interesting as I am aware of the requirements but there are some times when PPE works as the solution. The windows would be nice in many ways but not so easy to sell to management.

@ Jerry: Let me preface this mesage with the fact that I am a technical advisor for a infrared window manufacturer. I have been a thermographer for almost 17 years and you would be surprised at the return on investment (ROI) that windows provide If you look at the time spent by the thermographer and two electricians "waiting" on covers to be removed, the cost of the installation and the windows is recouped in as little as one inspection cycle!


And.....OSHA 1910.333 states that:

(a) that workers should not work on live equipment (greater than 50 volts) except for one of two reasons:
1. De-energizing introduces additional or increased hazards (such as cutting
ventilation to a hazardous location)
OR
2. Infeasible due to equipment design or operational limitations (such as when
voltage testing is required for diagnostics).

It must be understood that financial considerations are NOT an adequate reason to work on or near energized circuits. Management indicating that it is cheaper to work it "hot" is just not acceptable anymore.

The arc flash boundaries and training requirements detailed in NFPA 70 E & & B for "qualified personnel" is usually enough to make the windows extremely attractive.

The windows work on some of the more modern switchgear and MCC's but much older gear is not conducive to thier installation and use. One needs to look at the manhours required to install the windows and the window cost compared to opening the door. Yes one would need to suit up but after that it moves along pretty quickly. In addition, opening the doors allows you to inspect for cleanliness.

OSHA & NFPA 70E compliance..... are open cabinet energized inspections a thing of the past? what can you do to ensure compliance without interrupring production? How often should infrared/ultrasonic inspections be carried out? Infrared inspections windows and ultrasound ports provide a critical piece to this puzzle all while keeping the cabinet in a fixed & guarded condition (per NFPA 70). Check out some of our case studies and white papers @ IRISS.com.

What do you think about this Electrical Preventative Maintenance article?

Also do you currently carry out an Electrical PM? any PM at all? what do you think should be added to the PM list? I value your comments, ideas and stories.

Handling travel pay

Both the Internal Revenue Service (IRS) and the Department of Labor (DoL) have requirements that need to be met when considering compensable travel pay. The requirements for this segment of pay have to be met from gross pay and overtime calculation.Many components go into making this calculation. Factors such as one day assignment but overnight concerns, waiting time, meeting and training regulations come into play. Making these calculations rightly is important to meet the requirements set out…See More
