DTR Transformer Tap Changer Controller
DTR Transformer Tap Changer Controller

The transformer tap changer controller DTR controls automatically
the transformer on load tap changer, so that the power supply
voltage is practically constant, independently from the load.
In order to achieve this, the DTR is able to increase and decrease
the OLTC in the power transformer.


Applications
  • Control power transformer OLTCs to regulate voltage

    • Protection and Control
  • Automatic voltage regulator
  • Automatic/manual operation
  • Three setting tables
  • Configurable inputs and outputs
  • BCD format inputs to detect tap changer position

    • Monitoring and Metering
  • I, V, P, Q, cos j, frequency measurement
  • Transformer OLTC position
  • Event recording
