The REG-D/DA series of voltage regulators for control of transformer tap changers have become the smart standard on many sites around the world. Integrating well-developed software with a useful and reliable hardware package – the REG-D and REG-DA have proven track records within the industry, and are the benchmark for reliability and performance.

The REG-D® voltage regulator from A. Eberle allows both very simple and highly complex measurement, control and regulation tasks for tapped transformers. The REG-D can also be used as a transformer monitor as per IEC 60354 or IEC 60076, as a transducer, recorder, statistical unit and ParaGramer.

At a glance

• Very flexible - easily adapted to your specific requirements - for example:
  • can be used for control of a single transformer, or networked to others to provide a range of advanced transformer paralleling routines
• Recording and measurement with SCADA option provides a comprehensive transformer control solution
• Optional statistics and transformer monitoring mode, oil temperature, hot spot and transformer life calculations 
• Standard REG-D offers 16 binary inputs and 10 relay outputs
  • A further 16 binary inputs and 8 relay outputs can simply be added, with further expansion also possible
  • Optional mA and PT100 input allow the REG-D to interface to BCD, mA and Resistance type Tap Position Indicators and PT100 or mA oil temperature sensors
• Supports a wide range of SCADA protocols, including DNP Serial, DNP-iP, MODBUS RTU/TCP and IEC 61850
