We present our clients with High Voltage Combined Instruments Transformers upto a range of 145 kV. The current section of transformer is contained in a live chamber while the voltage section is housed inside the lower tank. This helps in cost reduction by sharing common porcelain housing and minimizing the requirement for oil and mounting structures. The current transformer can accommodate upto 5 cores with a maximum current of 4000 A and 3 windings can be provided for the voltage transformer upto a maximum thermal burden of 2500 VA. Insulation oil-paper combination based and the oil impregnation is commenced while maintaining a high degree of vacuum with precise monitoring and control of dissipation loss factor tan delta. They can be designed in conformance to IS, IEC, BS and ANSI standards as per the clients' specifications.
