Practical and safe plug solution

The FTS serves as a test block that facilitates the connection of substation devices, such as protection relays, fault recorders and, revenue meters to voltage and current transformers, as well as other equipment on the system side of a power grid.

The FTP is a specially designed test plug that is keyed to a specific configuration of FTS test blocks. When inserted into the corresponding test block, the FTP plug isolates the substation devices from the equipment on the system side. Additionally, it enables the connection of test equipment for conducting secondary injection tests.
