FTL testblock with dust cover and current disconnect pinThe FTL is a test block for interfacing substation devices (protection relays, fault recorders, revenue meters, ... ) to the voltage and current transformers and to other equipment on the system side of a power grid. The FTL test block uses disconnect pins to isolate the substation devices from the system side equipment. Once isolated, secondary injection can be performed using banana jacks on the front side of the test block.
