We manufacture high tesnion potential transformers (up to 11KV), with dry type resin cast (single phase and three phase) for indoor applications.The primary and secondary winding of potential transformer is magnetically coupled by a core. PT is used to step down the system voltage (3.3,6.6,11 KV) measurable upto 110/rt3, 110 V. The class of accuracy of metering PT is 0.2,0.5,1.0 and of protection PT is 3P.
