MULFI-38 Line fault indicator for MV underground distribution linesLine fault indicator for MV underground distribution lines
FEATURES
+The fault information will also be sent to SCADA system by external connection with IP Modem or RTU/FRTU.+When the sensors detect short-circuit and earth-fault, it transmits the fault information to display unit by cable immediately. Then the LED starts to flash, and the display unit send the fault signal to SCADA system by relay output or MODBUS at the same time.
+The fault indicator will also be shown on the Map location or Mimic diagram of SCADA system, it helps the user to identify the faulty section quickly.
