Product description
Product parameters
Reference standard: IEC61850, IEC60044.
Features:
● The analog unit （MU） can output IEC61850-9-1/2 optical digital message to test the optical digital relay protection device;
● Support network packet listening. It can listen to the message information on the network, select the APPID according to the intercepted information, and automatically match the selected SCD file;
● Optical serial port IEC60044-8 message transmission rate 2.5Mbps, 5Mbps optional, adapt to various relay protection devices under different technical requirements of State Grid Corporation and China Southern Power Grid Corporation;
● Polarity check function and nuclear phase function with optical digital SV control block;
● Supports SMV, GOOSE, and IEEE1588 packet monitoring. It can perform frame loss statistics on packets, and supports remote signaling, telemetry, and harmonic monitoring. Telemetry can be performed in vector mode.
