S40A is a type of 3-phase protection relay test kit, with 3×40A, 3×300V, and also a local control system. It is a portable and economic secondary injection tester, and easy to use. This 3-phase protection relay testing kit 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. Features ● 3*40A, 3*300V ● Additional 200mA ac current source ● Aux DC (24V, 110V, 220V) ● 4 binary inputs, 1 binary output ● Locally with color LCD
