How to make short circuit protection Relay | Overload protection

A short circuit is a normal connection between 2 nodes of an electric circuit intended to be at different voltage supply. This results in an electric current limited only by the equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire, or explosion.

When the relay is not powered on and the normally open contact has been closed, that is, the relay contact is short-circuit Working. automatically initiate the protective measures and the actions of the control circuit testing.

Protection relays use various sensing elements, such as current transformers & voltage transformers. to measure the electrical quantities of the power Line system.

A circuit diagram for a homemade Overload Protection and Short Circuit Protection system. You can use this circuit with a 6V DC or 12V DC power supply Line. This circuit is best suitable for use with a battery. This circuit Overload and Short circuits can result in overheating.

Short circuit protection Short Circuit is often a desirable feature to add to power amplifiers or power supplies. for both safety concerns and the protection of circuitry. A common example of a short-circuit is when the positive (+) and negative (-) terminals of a battery or Power Supply Line are connected with a low-resistance conductor. like a wire. In this condition, the battery or Power supply can be set to fire and can even explode.
