Surge Protective Devices Awareness

Surges, or transients, are brief overvoltage spikes or disturbances of a power waveform that can damage, degrade, or destroy electronic equipment within any home, commercial building, or industrial and manufacturing facilities.

Transients can reach amplitudes of tens of thousands of volts. Most equipment is designed to handle minor variations in their standard operating voltage. However, surges can be very damaging to nearly all equipment.

A typical building experiences multiple power surges every day.

In a 2017 Surge Damage Survey, ESFI surveyed electrical designers, electrical planners, and electrical engineers who worked in designing or renovating electrical systems in industrial facilities, healthcare facilities, and IT centers. Surge protection has been required by the National Electrical Code (NEC) since 2014, but ESFI’s survey results revealed that about one-third of clients who declined surge protection for their facilities did so due to a lack of concern about surges, while another third of clients believed that current available surge protection technology is inadequate.
