Profile: Indian Transformers Company Ltd manufactures instrument transformers (current & voltage transformers) of high and extra high voltage classes up to 400 kV. We also manufacture precision voltage, high power voltage and testing transformers. We specialize in manufacturing high voltage instrument transformers up to 245 kV. We can offer a wide range of voltage classes from 11 kV up to 245 kV. We also offer combined instrument transformers up to 132 kV class. High power voltage transformers (HPVTs) manufactured through the voltage class 245 kV are specially designed to provide remote location station power needs up to 100 kVA as well as relaying performance and metering accuracy of 3P and 0.2% as per IEC with burdens up to 400 VA. The insulation is finely graded and consists of oil-paper combination. The oil impregnation is done under a high degree of vacuum with monitoring and control of dissipation loss factor (tan delta). All HPVTs are hermetically sealed, with either stainless steel bellows or nitrogen cushion. We offer ultra precision voltage transformer for using as standard for accuracy measurements in laboratories. Precision voltage transformers are made with low excitation current requirement with accurate step down for the entire voltage range of 11 kV through 245 kV. High voltage transformers for power frequency tests on insulation are available for up to 300 kV, 300 kVA. The design consists of two stage cascade transformers of 150 kV each housed in a single FRP cylindrical shell.
