How to Calculate Knee Point Voltage of Current Transformer?
What is the knee point voltage of CT? The knee point is defined as the voltage at which a 10% increase in applied voltage increases the magnetizing current by 50%.
What is the Use Of Knee Point Voltage?
In this article we will discuss the use of knee point voltage of current transformer in the protection circuit. The knee point voltage of CT
