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 |
