On-load tap-changers voltage regulators, REG-D(A)

OLTC voltage regulators serve to maintain the required voltage at the terminals of the secondary winding of a transformer with an on-load tap-changer in automatic mode. In addition, the functionality of the REGSys ™ automatic voltage regulator range can be significantly extended with additional features.

Key features and benefits:

  • Large graphic LCD display, which displays all the necessary information: the position of the on-load tap-changer, voltage and other indicators.
  • Measured values: U, I, P, Q, S, cosφ, sinφ, f.
  • Multi-channel parameter recording function in the log.
  • Accounting and statistics functions: total number of switchings, number of switchings by positions.
  • Additional functions for monitoring the hottest point and lifetime.
  • Freely programmable binary inputs and outputs. Direct Pt100 input.
  • Voltage control of three-winding, phase-shifting transformers and transformer groups.
  • Support for communication protocols IEC 60870-5-101 / 103/104; IEC 61850; LON; DNP 3.0; Profi bus DP; MODBUS RTU; SPABUS.
  • Monitoring of transformers in accordance with IEC 60354/60076.
  • Possibility of programming the device for specific customer requirements.
  • All SCADA system capabilities (including IEC 61580) .
