Safety Test Switch (STS)

The apex in safety for power systems testing

The ST Switch ensures efficient isolation of the substation devices from the system side equipment by employing disconnect pins. This isolation enables the execution of secondary injection testing, which can be conveniently carried out via strategically positioned banana jacks on the front side of the test block.

To enhance operational transparency, the ST Switch incorporates built-in status windows. These windows enable operators to visually monitor and assess the opening and closing actions of the internal contacts during testing procedures.
