NFPA 70B, Recommended Practice for Electrical Equipment Maintenance, has championed the importance of an electrical preventative maintenance (EPM) program for years. Beginning in 1968 with requests to the National Electrical Code (NEC) committee for maintenance recommendations, 70B has more than 300 pages of valuable information on how to create and carry out an effective EPM program.

The importance of monitoring the quality of the electrical supply has increased with the ongoing push to boost uptime, productivity and profits. When carrying out business 24/7, having a process or operational interruption can negatively affect of the bottom line. If a customer can’t instantly purchase what they want from one company, a competitor is just a click away. READ MORE

While spaghetti adorned with one of the dozens of different sauces that are served in the small, off-the-beaten path restaurants in the Italian countryside is “splendido,” wiring that looks like spaghetti is just the opposite.

Fixing or mitigating the problem of equipment malfunction or misoperation due to incompatible power supply isn’t much more complicated than diagnosing the power quality problem. As May 2014’s article showed from Table 2 of IEEE Std 1159 2009, Recommended Practice for Monitoring Electric Power Quality, there are seven basic types of power quality phenomena. READ MORE

You are probably thinking this is yet another lecture about electrical safety. While focusing each May on safety is important, we should care about it every day. Unfortunately, preventable injuries and fatalities often occur when people fail to practice electrical safety.

Once a year, I focus on the latest trends and changes in power-quality monitors, standards and mitigation equipment. This article initially focused on the latter, but after researching several dozen of the newer products on the market, one thing became apparent. Customers often send me data from power quality monitors that seem to defy the laws of physics. READ MORE

Sometimes, a power quality investigation can lead you to see things that you aren’t really looking for and might be a distraction from what the customer wants you to do. But there is a point where you may also feel an obligation to tell the customer that there are more potential problems in their electrical system than just the obvious ones that you were called in to fix.

In this third part of my series on the most common power quality phenomena, I group several IEEE 1159 categories together under the general description of “distortion.” Though one might argue that all power quality phenomena result in distortions of the voltage sine wave, these are the more steady-state variety, including harmonics, interharmonics, notching, unbalance (or imbalance), voltage fluct READ MORE

Last month, we started the Top 10 in the power quality phenomena category with the most common disturbance: the rms variation. In second place are usually transients, those fleeting waveform changes that are far too brief to be seen by the naked eye in lighting. In certain cases, some power quality monitors aren’t able to capture them. READ MORE
