Transformers are one of the primary components for the transmission and distribution of electrical energy. Their design results mainly from the range of application, the construction, the rated power and the voltage level. The scope of transformer types starts with generator transformers and ends with distribution transformers. Transformers which are directly connected to the generator of the power stations are called generator transformers. Energypac’s standard range goes up to 520MVA and 400kV. The connection between the different high voltage system levels is made via network transformers. Energypac is able to offer network transformers up to 520MVA, 400kV.

Power Transformer
  • Designed to withstand short circuit forces acts radially and axially during faults.
  • High Efficiency ensured by implementing the recent developed technology of magnetic material and CU conductor.
  • Thermally upgraded insulation paper(Class A) results in Long
  • Lower PD value, Lower sound level
  • High withstanding capability against TOV, lightning strikes, Switching phenomenon, Over flux conditions.
  • Leak proof, Pressure and vacuum tested as per standard.

Transformers from 5kVA to 2500kVA and up to 36kV on the high voltage side and 3.6kV on the low voltage side are referred as distribution transformers. In the last step, they distribute the electrical energy to the consumers by feeding from the high-voltage into the low-voltage distribution network. These are designed either as liquid-filled or as dry-type transformers. All transformers of higher ratings are classified as power transformers.
