Motwane’s RTS Series, also known as Secondary Current Injection kit, is a portable and cost effective solution to test voltage & current based relays. It is designed with highly accurate digital meters for testing protective devices. The MOT-SIK set provides a high burden kit to test electromechanical relays. SIK series can provide up to 200A for CT and MCB testing. The compact & rugged design makes it easy to move it in the relay room.

Applications

The secondary current injection test of solid-state units can be performed by a specially designed power supply unit. Secondary injection tests are always done prior to primary injection tests. The purpose of secondary injection testing is to prove that the correct operation of the protection scheme is downstream from the inputs to the protection relay(s). It is done to minimize the risks during the initial testing of the LV side of the equipment. It should be noted that the secondary current injection method only tests the solid-state trip unit logic and components like a relay, miniature breaker, etc.
