Dry Type Distribution Transformer

Description:

• MPIL manufacture ventilated dry type transformer

• Maintenance free

• Safe from fire as material used are metals, ceramics, fiber glass and resin

• Environment friendly as there is no oil

• Handing becomes easier

• No chances of spillages and leakages

• Minimal non toxic smoke in case of fire

• MPIL offers ventilated dry type transformers with class H/E insulation which can bear heat upto 180/220ºC

• 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

• HV winding are of copper wire insulated with Nomex or suitable material for temperature rise

Advantages:

• High level of safety
• No flammable liquids
• No pollution from leaks solution
• No toxic off-gases
• 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
