Intelitek design a Parallel Operation of three-phase transformers that involves connecting two or more transformers to share the load while operating on the same electrical system. This configuration ensures greater flexibility , reliability and capacity in power distribution.

Parallel Operation of three- phase transformers involves connecting two or more transformers to share the load while operating on the same electrical system. This configuration ensures greater flexibility, reliability and capacity in power distribution.

To Operate transformers in parallel , certain conditions must be met:

  • Same Voltage Ratio: The primary and Secondary Voltages must match to avoid circulating currents between transformers.
  • Same Phase Sequence : Ensures that the transformers’ phase relationships align correctly.
  • Same Impedance: Impedances should be similar to ensure proper load sharing.
  • Same Polarity : To prevent phase opposition and resulting short circuits.

2 Nos. Transformer Three Phase 400/230V, 1 KVA, 50 Hz, air Cooled, Copper double wound with tappings at 50% on primary & secondary side. The Transformer will be housed in MS sheet box enclosure with top sheet and one side of MS Box should have window provision and having transparent acrylic sheet to see the internal parts.
