Distribution transformer vs power transformer


Power Transformer

Distribution Transformer

Power transformers are utilized in transmission network of higher voltages for step-up and step down application (200 kV, 400 kV, 66 kV, 110 kV, 33kV) and are generally evaluated over 200MVA.

Distribution transformers are utilized for lower voltage conveyance systems as a implies to conclusion client network. ( 6.6 kV, 11kV, 440V, 3.3 kV, 230V) and are generally appraised less than 200 MVA.

Power transformer is utilized for the transmission reason at heavy load, high voltage more prominent than 33 KV & 100% effectiveness.

The distribution transformer is utilized for the conveyance of electrical energy at low voltage as less than 33KV in industrial reason and 440v-220v in domestic reason

Power Transformers are utilized in Transmission network so they don’t straightforwardly interface to the customers, so load variances are exceptionally less.

Power Transformers are utilized in Conveyance Network so specifically associated to the consumer so load vacillations are exceptionally high

Power transformers are utilized for transmission as a step up gadgets so that the I2r loss can be minimized for a given power flow

Distribution transformers clearly cannot be planned like this. Subsequently the all-day-efficiency comes into picture whereas planning it.

The most difference between power and distribution transformer is distribution transformer is outlined for greatest efficiency at 60% to 70% load

Distribution Transformer is utilized at the distribution level where voltages tend to be lower
