What is short circuit protection circuit?
Short circuit protection is protection against excessive currents or current beyond the acceptable current rating of equipment and it operates instantly. As soon as an overcurrent is detected, the device trips and breaks the circuit.
How does a fuse make a circuit safer?
The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit.
What is a short circuit protection device?
Short Circuit Protection Devices To protect the devices and people from short circuit hazards , protecting devices are used in electrical circuits. These devices can detect the faults and trip the circuit immediately before the surge current reaches to the maximum.
What are the causes of a short circuit?
Many factors can lead to a short circuit. The following are some of the most common causes: Damaged or old insulation normally makes the live wires, and neutral come in contact, which can result in short circuit. Screw and nail can make insulation to damage and create short circuits.
What happens if there is a short circuit?
A short circuit is simply a low resistance connection between the two conductors supplying electrical power to any circuit. This results in excessive current flow in the power source through the ‘short,’ and may even cause the power source to be destroyed.
What are the effects of a short circuit?
Effects of Short-Circuit. When a short-circuit occurs, the current in the system increases to an abnormally high value while the system voltage decreases to a low value. The heavy current due to short-circuit causes excessive heating which may result in fire or explosion.
