This International Standard applies to alternating current gas-insulated metal-enclosed disconnectors for rated voltages of 72,5 kV and above.
This standard provides test requirements for gas-insulated metal-enclosed disconnectors used to switch small capacitive currents (no load currents) such as occur when sections of busbars or grading capacitors are energized or de-energized.
NOTE- Simultaneous switching of disconnectors in the same circuit is not advisable and thus not
considered in this standard.
