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.

amrest manufactures indoor type resin cast, outdoor type oil cooled current transformer with metering, protection and special protection purposes. The standard value of the secondary current in ct is 1a or 5a. The standard value of rated burden is up to 30va. (2.5va, 5va, 7.5va. 10va, 15va, and 30va) accuracy of class in metering ct is 0.1, 0.2, 0.2s, 0.5, 0.5s, 1.0 or 3. The standard accuracy class in protection ct is 5p, 10p or 15p and the accuracy limit factor 5, 10, or 15. The special purpose of current transformer applications is balanced protective system and distance protective schemes. The requirements of ps class are rated knee point voltage and maximum exciting current at the knee point voltage and the resistance of secondary winding at 75° c.

Oil Cooled Transformer adjust the level of voltage up and down as per requirement. Their main objective is to form a compatibility in voltage supply and varied appliances for which it is working. If the voltage required for application is lower than voltage supply then its job is to bring the level down as cooled transformer. If the voltage required is higher than voltage supply then the job of transformer is to raise its level.

Transformer oil or insulating oil is usually a highly refined mineral oil that is stable at high temperature and has excellent electrical insulating properties. It is used in oil-filled power transformers, some types of high voltage capacitors, high voltage switches and circuit breakers. Its function is to insulate, suppress corona and arcing, and to serve as a coolant.The easiest way to explain the reasoning for proper transformer oil maintenance is to compare a Transformer to a car. A car requires oil for lubrication while a Transformer requires oil for insulation and cooling. Just as a car requires regular checks of both oil quality and oil level, a transformer requires the same proactive treatment. Oil in each instance degrades over time resulting in the potential for failure or costly repair bills.

The transformers are built in accordance with IEC 60076 standards (or other International standards) and with efficiency as per EN 50464-1.

• Range: 25 kVA - 3150 kVA

A wide range of distribution and medium power transformers. These transformers can be free breathing or hermetically sealed. Conventional transformers are fitted with a conservator with breather for free breathing while hermetically sealed are without breathing with bolted cover. Wide range of transformers in accordance to above standards with different combinations can be manufactured. The transformers are generally designed and manufactured to comply with the IEC publications 60076.

Adding on to the basic functions of every transformer, Air/ Oil Cooled Transformers adjust the level of voltage up and down as per requirement. Their main objective is to form a compatibility in voltage supply and varied appliances for which it is working. If the voltage required for application is lower than voltage supply then its job is to bring the level down as cooled transformer. If the voltage required is higher than voltage supply then the job of transformer is to raise its level. Measures of the ratings in Transformers are always consider in KVA units. These depend current delivered by unit and on input & output voltages. We offer high quality Air/ Oil Cooled Transformers which relatively precision engineers and simply designed to provide exact ratio of windings in each circuit. This enables delivery of accurate voltage and current as per the application. The usage must be specified prior to installing a particular transformer in order to attain smooth operation and longer functionality.   We rigorously test our range of Air/ Oil Cooled Transformers on the basis of industry leading norms and standards for enhanced demand in market and complete client satisfaction.
