Define distribution transformer

Short answer

A distribution transformer steps down the primary distribution voltage (11 kV or 33 kV) to the consumer utilization voltage (400/230 V). It is usually pole- or plinth-mounted, rated 25–500 kVA, and designed for low core losses and high all-day efficiency as it remains continuously connected.

With respect to a distribution system, define distribution transformer.

A distribution transformer is the step-down transformer that converts the primary distribution voltage (11 kV or 33 kV in Nepal) to the consumer utilization voltage (400/230 V). It supplies the secondary (LT) network.

It is usually pole-mounted or plinth-mounted, rated about 25–500 kVA (for example 11/0.4 kV, 100 kVA, Dyn11). It is connected all the time, so it is designed for low core (no-load) losses and high all-day efficiency.
