Description
When the test plug is inserted, the CT circuits are short-circuited automatically, so the secondary winding is never opened under current. The sequence of inserting and withdrawing the contacts is arranged so as not to cause false trips. The blocks are installed in protection cabinets next to the protection terminals. The test set is connected through them without disconnecting wires from the terminals.
