MATCHING CURRENT TRANSFORMERS

Graphic2-5-2For differential protection relays we developed and supplied 44 ratios matching current transformers for WAPDA panels. Various combinations of windings on terminal plate can give the required ratios. The current rating is 1 Amp and 5 Amps. Other details can be supplied on demand.

ROUTINE TESTS:

  • Measurement of ratio and phase angle error and accuracy class.
  • Polarity checking.
  • One minute voltage withstand test on primary.
  • One minute voltage withstand test on secondary.
  • Insulation resistance.
  • Visual inspection.
