In attempting to explain to a colleague why we care about negative sequence components, I tried to follow the guidance that Bob Lawrie, another member of the NFPA 70B Electrical Equipment Maintenance committee, offered to me many years ago: never use a formula in an article. While engineers may take joy in formulas and math, the general public typically does not. READ MORE

In preparing to write my next article, I often review the topics I have covered in the past year or so, and I consider the issue’s theme. Being a sometimes overly analytical engineer, I keep track of just about everything in a spreadsheet, from the topics of ELECTRICAL­ CONTRACTOR articles, to budgets to my home’s utility bills.

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.

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
