Transformer Oil Dielectric Strength Test

The transformer oil or insulating oil is used in transformers as well as some electrical equipment to:

insulate the live parts,
maintain insulating properties of the material such as paper, winding, etc. used in the machine,
protect the machine parts from rust and corrosion,

increase the heat dissipation of the machine by convection,

The WTI means winding temperature Indicator and OTI means Oil Temperature Indicator which indicates the winding temperature & oil temperature of the transformer and operates the alarm, trip, and cooler control contacts. This instrument operates on the principle of thermal imaging and it is not an actual measurement.

Buchholz relay is a safety device which is generally used in large oil immersed transformers (rated more than 500 kVA). … It is used for the protection of a transformer from the faults occurring inside the transformer, such as impulse breakdown of the insulating oil, insulation failure of turns etc.

The pressure relief valve (PRV) is designed as a safety device to be used on power transformers and similar oil filled electrical equipments. When pressure in tank rises beyond predetermined safe limit , the PRV operates and performs following functions .
