Amrest manufactures  outdoor oil cooled (single and three phase type) Voltage Transformer with metering, protection purpose. Amrest also manufactures of three phase residual voltage transformer, the standard value of the secondary voltage in PT is 110V or 110/3 the value of rated burden is 10VA to 500VA at a power factor of 0.8 lagging. The standard accuracy of class for measuring PT is 0.1, 0.2, 0.5, 1.0, or 3. The standard accuracy of class for protective PT is 3P and 6P, the standard accuracy of class for three phase residual voltage transformer is 5PR and 6PR, The voltage factor to be specified are different.

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.
