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.
From 2017 to 2023, surge protective devices have undergone major changes in the requirements set by the National Electrical Code. These changes are designed to
A recent survey by ESFI and NEMA found that power surges are responsible for over 1/3 of unplanned outages and downtime in facilities across the
Power surges can happen anywhere. But 60 to 80% of them originate from equipment inside our buildings and facilities. Power surges can be caused by
Surge protective devices are required for emergency systems and for areas of nursing homes and limited care facilities used exclusively as patients’ sleeping rooms. SPDs
