Draw Out Potential Transformer

Fixed or horizontally with drawable voltage transformer are accommodated on top of the cubical or in separate PT panel and are in 3 limb or 5 limb or 3 single phase version with ratio to suit system voltage. The PT winding are epoxy cast resin insulated and are connected to either circuit side or busbar side as desired. The voltage transformer carriage can readily be removed from the panel when required. A shutter automatically covers the fixed isola_ng contact when the voltage transformer is isolated. On the primary side of voltage transformers are provided with high resistance cartridge type fuse which can only be removed when the transformer is isolated. Secondary of HRC fuse are also accessible.
