Switching Transients or Transient Recovery Voltages may occur in certain situations and events occurring frequently in normal operations of a MV or HV industrial or commercial Power System. They may not be fatal in their first occurrence but prolonged exposure to transients will reduce lifespan of power system equipment. They may also disturb the stability of the power system putting the entire installation at a risk of shutdown or failure of certain equipment.
A snubber circuit is a proven way of reducing these transients and ensuring the protection of individual equipment and the wider system. Therefore, snubbers find their applications in many areas in a power system, in most cases becoming an indispensable component of it.
