In this system of earthing, the neutral point is earthed through the primary winding of a single-phase voltage transformer as shown in the figure below. The secondary winding of the voltage transformer is connected in series with…

Generally, at every voltage level, the neutral point is available from the generator or transformer i.e., when the star connected. But when there is a delta connection or when the neutral is desired on the busbars etc., then the …

The resistance offered to the lightning current when the tower is directly exposed to lightning is called tower footing resistance. It is the value of footing resistance measured at 50 Hz. The performance of the line purely depen…

When the neutral of the system is directly connected to the ground with negligible resistance and reactance between them, then the grounding system is known as solid grounding or effective grounding. A system is said to be solidl…

The system in which the neutral point is grounded through a current limiting device (resistor) is known as a resistance grounded system and the grounding is referred to as resistance grounding. This method is used when it becomes…

The system in which the neutral point is grounded through impedance which is highly reactive is known as reactance grounded system and the grounding is referred to as reactance grounding. Necessity of Reactance Grounding : If s…

The neutral grounding is nothing but connecting the neutral point of the supply system or rotating machine or transformer to the earth directly or through some circuit elements. A three-phase system can be operated in two ways, t…
