Application :

Role of Combined CT-PT Unit in electrical systems is of prime importance as they are the means of stepping down current and voltage to measurable values. Secondary current and voltage is of proportionately lower value to the primary current and voltage. Combined CT-PT Unit can thus be used with ammeters and voltmeters for the measurements of current and voltages.

Basic Feature :

• Maximum utilization of space can be achieved as it omits the need to install separate CT and PT's
• To reduce primary current and voltage to a measurable value
• To protect electrical systems with the help of relays
• To reduce risk to humans by isolating measuring side from high Current/Voltage side

Design Criterion

As the name suggest, a CT-PT combined unit consists of CT's and PT in one single tank. This eliminates the need to install separate CT's and PT's thereby saving space and reducing cost. The primary winding of the CT is made of copper rope with necessary number of turns. The secondary winding consists of core made from CRGO(Cold Rolled Grain Oriented).Super enameled copper wire is uniformly wound on core with the help of toroid winding machines.

The CT-PT unit is dried and filled with filtered transformer oil under vacuum

The metal parts can be painted or galvanized as per customer requirement/specification. All fasteners used are Hot-Dip galvanized. Stainless steel fasteners can be used on request.

The unit can be supplied with meter box, secondary leads and G.I. Pipe.
