The major difference B/W Ptr and DTr ,
* The power trans is step down and step up the High voltage
(HV-3Phase to 3Phase system)-for substation purpose
* The power trans have rating up to 500mVA(up to 400kV)
* The Distribution trans is step down voltage(HV to LV
Side -3Phase to 3Phase 4 wire system)-for domestic consumer
* The power trans have rating up to 50mVA(33,22,11kV to
0.415kV
