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%.
Electrical
What is Knee Point Voltage of a Current Transformer (CT)?
In this article we will discuss importance and use of knee point voltage of current transformer in the protection circuit. The knee point voltage of
Why CT Secondary Should Never Be Open? (Hazards & Theory Explained)
Open-circuited CT can cause serious safety concerns like fire, electrocution, and protection failure. Therefore, you must ensure that CT secondary should always closed-circuited. Let us
Why V/f Ratio is Kept Constant in VFD?
In VVVF drive, the V/f ratio is kept constant to maintain the rated flux in the motor. The higher V/f ratio causes the motor’s core to
