This group is providing calibration facility for High Voltage DC equipments i.e. DC High Voltage probe, DC High Voltage divider, DC High Voltage Power Supplies and DC Volt meter, upto 100 kV. Primary standard of DC High Voltage is the Resistive Divider, which is traceble to Josephson voltage standard.
The facilities for high current and shunt resistance measurement (at high current) have been established. Shunt resistance can be measured low up to 0.001Ω at 600 A with an uncertainty of 10 to 15 ppm.
