Current and Voltage Instrument Transformers – Technical and Applicaton Guide

Instrument transformers (ITs) are designed to transform voltage or current from the high values in the transmission and distribu- tion systems to the low values that can be utilized by low voltage metering devices. There are three primary applications for which ITs are used: metering (for energy billing and transaction purposes); protection control (for system protection and protective relaying purposes); and load survey (for economic management of industrial loads).
