• Burden Compensation

The model 7023/4000 series of High-Voltage Current Transformers was designed for the current input to MI’s 300 kV Loss Measurement System. This design meets the requirements of both IEC and IEEE standards for testing power transformers. C57. The bushings are filled with insulating gas and fitted with a pressure indicator or with an optional pressure transducer with a 4-20 mA output for continuous monitoring. Connections to the primary window winding of the current transformer are made via a copper bar rated to handle high current up to 4000 A.
