WG 35

High-voltage switchgear and controlgear- Part 214: Internal arc classification for pole-mounted switchgear for rated voltages above 1 kV and up to and including 52 kV

This standard will specify the requirements for internal arc classification for pole-mounted switchgear used for alternating current of rated voltages above 1 kV and up to and including 52 kV in outdoor pole-mounted installations, and for service frequencies 50/60 Hz. Enclosures may include fixed and removable components and may be filled with fluid (liquid or gas) to provide insulation. This standard will not cover other open-terminal metal-enclosed switchgear than pole-mounted switchgear.
