Cast Resin Transformer Dealers in Delhi (12 products available)

We are offering indoor epoxy resin cast current transformer upto 33 kv.

• Type: Current Transformers
• Application: Power Grade
• Condition: New
• Brand Name: AMREST

amrest is the manufacture of mv outdoor resin cast current transformer upto 33kv class. amrest manufacture outdoor dry type current transformer as per customer requirment for metering and protection purpose. Avilable metering and production class as both in a current transformer or seprate metering and protection as per requirment. a current transformer is designed to convert the primary rated current which flows through the primary winding. the secondary winding must generally be short circuited at any time, otherwise dangerous high voltages can occur at the secondary terminals. the secondary connected devices are connected in series.  

A Current Transformer is the measuring device for metering and protection system. The primary current of the CT is transformed into the required secondary current of 5 A or 1 A. Measuring CT's have different class of accuracy I.e. 0.1, 0.2S, 0.2, 0.5S, 0.5 and 1.0 and protection CT's have 5P10, 5P20 and 10P10. In the case of special protection CT's(PS class), the Knee Point Voltage(KV) of the CT is specified along with secondary resistance and magnetizing current. The construction of the CT not only depends upon the ratio but also on the Short Time Current Rating, Burden and Class of Accuracy.

The transformers are built in compliance with IEC 60076-11 standards and, IEEE C57.12.01 (or other on request). The core is made of cold rolled oriented grain steel sheet with low specific loss, cut at 45°C, step-lap, assembled at interleaved joints, with high care. It is calculated to obtain the minimum residual flux, reduced inrush current, low noise, low iron loss.

Transformers are electric equipment that changes the voltage and the current of electricity to facilitate its efficient transmission and distribution. Transformers are commonly used at power generation facilities to increase voltage and to decrease current in order to transport electric energy across transmission lines. When the electricity reaches the end user, transformers are used to reduce voltage and to increase current to make the electricity suitable for general use. The process of transforming voltage results in energy loss that is released in the form of heat and therefore transformers must contain effective cooling systems. Transformers are differentiated by their cooling systems (this is one of several ways that the transformer industry classifies its products). Dry type transformers dissipate heat directly into the ambient air. Liquid cooled transformers (e.g. oil filled transformers) dissipate heat into liquid mediums.
