This device is intended for transmission and reception of RP and SIPS commands over power line communication channels of 110–750 kV transmission lines.

Main function

  • Transmission and reception of up to 32 RP and SIPS commands over power-line communication channels
  • Transmission of telematics signals at a speed of 200 baud (on the 2 kHz commands transmission band)
  • Continuous monitoring of power-line communication channel
  • Time synchronization of the transmitter and receiver with an accuracy of 2 ms
  • Continuous monitoring of all nodes and units, including transmitter’s input circuits and output circuits of binary outputs of the receiver
  • Registration of all events in a non-volatile event log
  • Displaying of current pilot signal level
  • Displaying of margin for overlapping attenuation
  • Connection to the substation’s APCS under the IEC 60870-5-101 and IEC 60870-5-104 protocols

Distinctive features

  • Generation of commands using two-frequency parallel or single-frequency code
  • Transceiver tuning over the entire range of operating frequencies without replacement of any units
  • Continuous measurement of level of interferences in the power-line communication channel
  • Triggering of alarm when the predefined interference threshold is exceeded
