RANGE: Upto 5 MVA 33 kV Class

Product Range
50 kVA to 5000 kVA, 11 kV & 33 kV Class suitable for Indoor applications with off circuit tap links, off circuit tap switch, on load tap changer (Indigenous & Imported).

Standards
The Dry Type transformer are manufactured to comply with National International Standards BIS, IS 11171, IEC 76.


Quality
MUSKAAN’S products are certified for ISO 9001 : 2000 by NABCB. MPIL has set up a complete quality management system to offer the best customer satisfaction.


Description
MPIL manufacture Ventilated Dry Type Transformer are totally maintenance free and safe from fire as material used are metals, ceramics, fiberglass and resin It is environment friendly as there is no oil, hence handing becomes easier and there are no chances of spillages and leakages and there is minimal non toxic smoke in case of fire. 


MPIL offers Ventilated Dry Type Transformers with class H/E insulation which can bear heat upto 180/220 degree C and can be used in humid and chemically polluted atmosphere.


Winding
LV & HV Winding are done in dust free air conditioned winding shops. Rectangular copper strips are used for LV winding insulated with Nomex while HV winding are of copper wire insulated with Nomex or suitable material for temperature rise if wrapping is not possible due to small diameter. 

Testing
All transformers are tested for routine test. MPIL has in-house facilities for conducting all routine tests as per IEC & IS.

Advantages

 
  • High level of safety
  • No flammable liquids
  • No pollution from leaks solution
  • No toxic off-gasses
  • Can be placed close to the load
  • More efficient
  • Increased emergency overload capability
  • Improved reliability
  • Low Noise and low maintenance
  • Easy to repair (open coils)
Routine Tests
 
  • Measurement of Winding Resistance
  • Measurement of Voltage / Turns Ratio
  • Measurement of Impedance Voltage / Short Circuit
  • Impedance & Load Loss
  • Measurement of No Load Loss & No Load Current
  • Measurement of Insulation Resistance
  • Di-Electric Tests
 
Environmental Impact Operation Aspects
 
  • Transformers insulated with Nomex brand materials are extremely safe, even when exposed to fire
  • High flame resistance, & low smoke and no toxic off-gasses
  • Class H & E ventilated dry type transformers can be built smaller, reducing the footprint to the environment, conserving space

  • Insulation is friendly to use during manufacturing-no skin irritants or surface chemicals
