PRODUCTS OFFERINGS


We are capable of manufacturing Customized Instrument Transformers as per requirements upto 33KV rated voltage for applications in Switchgear Manufaturing (Indoor Type) and Power Utilities (Outdoor Type).

Our products are highly accurate and reliable for Metering and Protection purpose.

Outdoor type Current Transformer (CT)

We manufacture Single phase Oil-cooled current transformer upto 33KV for outdoor applications purpose. Our CT’s are highly reliable and accurate for metering and protection purposes. We customize all the parameters as per the Coustomer’s requirement. We can manufacture all range of required accuracy classes starting from 0.1 Class with current Levels upto 1200 A and above.

We have 3 type of designs for Oil Cooled Outdoor type CT’s.

• Live Tank type - In Live tank design is a single bushing design which is high on performance. In this design top of current transformer is at high potential and Core- Coil assembly is placed in the top tank of the transformer.

• Dead Tank type - This design is double bushing design and most commonly used. It is reliable and easy to handle and has lesser leakage points.

• Dead Tank Top-Bottom Design - This design is single bushing design, it comprises of top tank and bottom tank but unlike Live tank the core-coil assembly is placed at the bottom tank, This design is more stable as bottom tank is heavier than the top.

Epoxy Resin Cast Transformer (M.V)

Resin cast Current Transformers

We manufacture Epoxy Resin cast Current Transformer upto 33KV of following types :

• Slot CT/ Window CT - This type of Current transformer does not have primary winding andis mounted in line with the bus bars (bolted on both sides). The bar type CT is fully insulated to the switchgear voltage. A window type CT has the incoming or outgoing insulated / shielded cables pulled through it. The high voltage shielded cables are pulled through the hole or ``window`` in the middle of the CT.

• Bar type CT - This type of current transformer consists of a bar of suitable size and material forming a integral part of the transformer.

• Wound Type CT - In This type of This type of CTs have a primary winding of more than one full turn wound over the core of Current transformers. The magnitude of the secondary current is dependent on the turns ratio of the transformer.

Technical Specifications : - Accuracy class 0.1,0.2s,0.5,1,3P,5P.

Primary Current ratings:- 5 A to 3200 A and above

STC level :-upto 50 KA for 3 second

IS/IEC
