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 & there is minimal non toxic smoke in case of fire.
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


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
