advantages of Collection for high-voltage switchgear

High Voltage Switchgear (HV) The power system which deals above 36KV is called HV (high voltage) switchgear. When the level of voltage increases then the arcing will be generated as the switching operation is extremely high. As a result, during the designing of this equipment, special care has to be taken.
