    Manufacturing process

    Three limb core construction is used. Core sheets are made from cold rolled grain oriented (CRGO) silicon steel sheets. Fibre- glass tape banding hold the core tight and reduce the noise level. Treatment given to the completed core protect it from atmospheric corrosion.

    Both the HV and LV windings are made from copper conductors. On the LV side copper foil is used depending on current to be carried.The advantages of these windings are reduction of  extra losses, balanced temperature distribution within the winding and high short circuit capability.On the HV side, this is the heart of dry type transformers. The production of HV applications only using vaccum-encapsulated moulds. The interconnection between HV phases are obtained by links made out of copper tubes with their ends  formed into lugs.

    Protection against overload or high winding temperature can be provided by thermistors. Alarm and trips are also provided. 

Routine testing
    The required routine tests are carried out in plant by trained personnel using modern, calibrated digital test equipment.

    These tests includes;
        Ratio and vector group
        Insulation resistance
        Applied voltage
        Induced overvoltage
        No load loss
        Full load loss
        Partial discharge
