Digital Relay Test Device

Main Features:Combining the test of IEC61850 Optical Digital with the test of small signal analog, it also can be attached by external current and voltage amplifiers. 4-Phase Optical Transceivers, providing effective code which in connection with various communicated information according to IEC61850 standards. Parsing the documents of protected mode completely, and implementing the configuration of Current&Voltage channel selections,Scale factors,quantities of ASDU,Sample rates,GOOSE information etc. Two outputs of separated 12-channel analog small signal, complaint in testing various protections against accepting electronic transformer signals; or connecting all brands of power source, which aims to test the general protection and digital protection contrastively. 8 binary inputs, 6 relay binary outputs, 2 transistor binary outputs, GOOSE information messages, implementing the full closed-loop test of protection.
