Ponovo 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 micro-processor based protection, and on starting value, quick‐break value, harmonic blocking
value and manual synchronization of micro‐processor based transformer differential protection.
S40A is an ideal secondary injection tester for all power utilities, power plants, relay manufactures, panel manufactures, research institutes, universities, testing companies, etc.
Features:
