FMs Share Insights On Power Surge Incidences, Surge Protective Devices


Transient overvoltage events, more known as surges commonly, were cited because the third leading reason behind downtime in a recent survey of commercial and industrial facility professionals, which includes managers, owners, building engineers, heads of maintenance, and associated occupations. The Electrical Safety Foundation International (ESFI) and National Electrical Manufacturers Association’s (NEMA) Low Voltage Surge Protective Devices Section (BI-VS) recently surveyed these professionals concerning power surge incidences, misconceptions , and using surge protective devices within their facilities.

Surge protective devices were seen as a success by most respondents, as 79% approximated that downtime and equipment failure has been significantly reduced. Almost all survey respondents (72%) claimed to end up being either very or extremely acquainted with power surges, while only 8% had been only slightly or not familiar at all. Probably the most cited factors behind power surges were changing of electrical loads commonly, lightning, faulty wiring and/or connections, and harm to power lines.

In 2021, the Electrical Safety Foundation International surveyed commercial and industrial facility professionals, which includes managers, owners, building engineers, heads of maintenance, and associated occupations. These professionals provided insights concerning power surge effects and incidents, as well as using Surge Protective Devices in the facilities they manage. (Graphic: Business Wire)

In considering the main element findings, when questioned whose facilities had skilled unexpected downtime, 49% documented a power surge got caused this interruption in the last 12 months. Unexpected downtime had been common, with over 72% of facilities surveyed suffering from downtime lots of times per year. Twenty-three percent of respondents pointed out that they set up surge protective devices after going through a surge event. Thirty-four percent of unplanned power outages were due to power surges and unexpected misoperation or resetting of equipment. Equipment recently put into service borne the brunt of power surges that unsuccessful, with 78% having experienced service for five years or less.

Only surge protective devices, referred to as transient voltage surge suppressors also, drive back power surges. Typical power strips, consumer uninterruptable power supplies, ground-fault circuit interrupters, and breakers or fuses usually do not. Survey results show that setting up these devices shall drive back downtime, enhance system and data reliability, and decrease electrical failures to help keep your facility and electrical equipment running well.
