DRY TYPE TRANSFORMER WITH OLTC

VPI DRY TYPE TRANSFORMERS

  • PME manufactures Dry Type Transformers ranging from 25 kVA to 3150 kVA of voltage class up to 33 kV. These transformers are fitted in enclosures suitable for indoor installation (IP21, 23) as well as for outdoor installation (IP 45).
  • PME in association with EI Dupont USA manufactures Dry Type Transformers with certified insulation materials & system meeting the international standards for quality of design, manufacturing and performance as per IEC 60076-20.
  • The vacuum pressure impregnation technology adopted is superior to conventional oil filled & Cast Coil transformers as explained below.
Sr. No. Parameters VPI Cast Resin Oil Filled
1 Conductor Insulation Nomex Non-Woven Polyester Paper
2 Thermal Rating Class C Class F Class A
3 Process Conventional Winding with nomex insulation Cast Mould Conventional winding with press board insulation
4 Impregnation Resin (Vacuum Pressure) Resin (Vacuum cast) Oil (Vacuum)
5 Coil Strength Excellent Cracking of coils Poor mechanical strength
6 Over Loading Yes, due to Ventilation No Marginal
7 Repair Possible Not Possible Possible
8 Safety No Toxic Gases Partial Emission Emission of Toxic Gases
9 Partial Discharge No Average High
10 Pilferage No No Yes
11 Maintenance No No Yes
12 Short Circuit Strength Excellent Excellent Poor
  • These transformers are as per IS 11171/SAN 180 and IEC 60076-20.
  • The energy efficient transformers can also be supplied using Amorphous core & no load losses are reduced by 70%.
  • The winding temperature indicator is provided & operated by RTD placed in the winding. The terminations can be bushings/cable box suitable for cable sealing.
  • The tap changing is usually affected by means of links or off circuit switch provided with handle on enclosure.
