S40A Protection Relay Test Set S40A is a type of 3‐phase protection relay test set, with 3×40A, 3×300V, and a local control system. It is a portable and economic secondary injection tester, and easy to use. This 3‐phase protection relay testing set can apply to the testing not only on operating value and operating time of AC/DC relays, but also on complex voltage blocking directional over‐current, zero sequence over‐current, low‐frequency load shedding and other protection functions of low voltage line micro‐processor based protection and whole group transmission of high voltage line...
