Tanking and Testing

  • All the transformers are routine tested with relevant standard/customer specifications are conducted as per IS1180/IS2026/IEC.
  • TEST Lab facility for all Routine Tests with NABL Calibrated Equipment

Standard manufacturing practices

  • KPEL use only pre-compressed board material for insulation.
  • Axial and radial banding for sturdiness
  • Interleaved disc winding for 33 KV CLASS Transformers.
  • Layer type of winding for LV and HV coils for better impulse voltage distribution.
  • Proper distribution of clamping force for better clamping of windings.

Defined Routing of Tap and Line leads for better voltage distribution

  • Pre shrinkage of coil, smooth control of shrinkage force.
  • No further shrinkage of windings under short circuit forces in the system.
  • For core coil assembly, Pre compressed press board material/supreme grade insulating material is used.
  • Silver coated tap switches for high current transformers and linear tap switches.
  • Taps at winding middle for better ampere turn distribution and increased short circuit withstand.
