Gas Insulated Switchgear DETERMINATION

Passive determination of switching times for gas-insulated medium-voltage switchgear Normally, the breaker operating time and the contact resistances are measured on medium-voltage breakers. In addition, corresponding travel curves are also recorded in order to obtain conclusions about the state of the entire mechanism.
