Surge and protection

Damage  caused by electrical  transients  or surges is one of  the  main causes  of  electrical equipment
failure.An  electrical  transient is a short-lived, high-energy  pulse that is  applied to a normal power system
as  soon as the circuit suddenly changes.They can come from  a variety of sources, including the inside and
outside of the facility.
Surge Protection Device (SPD), also known as  Transient  Voltage Surge  Suppressor (TVSS), is  used to
transfer  high current surges to  the ground through the device, limiting the voltage applied to the device and
protecting the device.
