High-voltage switchgear and controlgear - Part 109: Alternating-current series capacitor by-pass switches

Is applicable to a.c. series capacitor by-pass switches designed for outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 000 V. It is only applicable to by-pass switches for use in three-phase systems. This specification is also applicable to the operating devices of by-pass switches and to their auxiliary equipment. This specification does not cover vacuum by-pass switches.
