High-voltage switchgear and controlgear - Capacitive current switching capability of air-insulated disconnectors for rated voltages above 52 kV1 Scope This technical report applies to high voltage air insulated disconnectors for rated voltages above 52 kV. The report describes the capacitive current switching duty and provides guidance on laboratory testing to demonstrate the switching capability. Air insulated disconnectors equipped with auxiliary interrupting devices are included under this scope. NOTE For manually operated disconnectors, the in service safety of the operator should be

Electrical insulating blankets are flexible sheeting made of elastomer or plastic material
