Distribution Transformer


Distribution Transformers

50KVA – 30MVA ABB and Schneider Transformers

Distribution Transformer or service transformer is a transformer that provides the final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer.

Description and Functionality

Design and supply of systems of medium and high voltage (up to 36KV), along with associated control and metering systems. Measurement transformers up to 550KVA. Isolating switches up to 550KVA. Steel construction and Bus-Bar system for high voltage switchyards. Polygonal or circular galvanized steel poles. Metal clad & metal-enclosed cubicles up to 36kv

Which transformer is used in distribution?

In electrical, step down transformers are used in electrical distribution system which works on very high voltage to ensure low loss and cost-effective solution for long distance power delivery requirements. To convert the high voltage to a low voltage supply line, Step down transformer is used.


Types of Distribution Transformers

  • Single-phase Transformers These transformers are specially used for networks where three-phase supplies are not required. Usually, they are used to repair overhead distribution loads in residential areas. They are also applicable in industrial lighting, light commercial loads and electrical applications.
  • Three-phase Transformer A three-phase transformer is used to hold electrical energy from the main distribution circuit to the auxiliary distribution circuit. It transmits current to the secondary distribution circuit and at the same time reduces the voltage of the primary distribution circuit. These transformers reduce the voltage supplied to the primary circuit based on consumer requirements.
  • Pole-mounted Transformer The pole-mounted transformers are mounted on a power pole at the height of the overhead cable. They are used to change high to low distribution voltage like 120/240 volts electricity. These transformers are widely used in rural areas, ranging from 16 kVA to 100kVA. They are small in size and easy to mount on single-pole structures.
