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 be closed-circuited. Let
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
