How Earth Fault Occurs. Normal faults occur in response to pulling or tension. If earth fault occurs the lamp will show dim light or goes out because potential is zero.
This is because if there is an earth fault the potential difference between the earth and line become zero so there wont be any current flow ie lap on that line off. It compares the incoming and outgoing current from the equipment along the circuit conductor. Voltage potential at the earth mat increases due to grounding.
If earth fault occurs the lamp will show dim light or goes out because potential is zero.
If there is an earth fault occur in one of the line suppose L3 the lamp connected in that line L3 off or dim and the other two lamps glow brighter. In California there are two plates - the Pacific Plate and the. Effects of Earth Faults. Every now and then accidents caused by electrical incidents injure many people.
