This is a surge protector.
Voltage surge protector circuit diagram.
Assortment of surge protector wiring diagram.
It s the connection between the hot power line and the ground wireline.
Surge protector circuit diagram the circuit diagram of a surge protector is shown below.
Surge protector or surge protection device is a device that will provide surge suppression or voltage spike suppression so that sensitive devices will not get damage.
However it is not limited particularly in ac grid lines.
Generally fuse or mcb is used for overvoltage protection however in this project our aim is to make a circuit which can perform better than a fuse or mcb and overcome the.
From the above simplified surge protection device circuit diagram common mode surge voltage appears between l pe and n pe.
A wiring diagram is a simplified traditional photographic representation of an electrical circuit.
It reveals the components of the circuit as simplified shapes and the power as well as signal connections in between the tools.
G1 and g2 are the gas discharge tubes.
This design is not great it s slow to act depending on a relay it will take many ms to switch off at current max relay current and a 250v mov in 120v installation won t help much either.
This circuit helps in protecting the equipment from the damage which is caused by transient surge voltages like strikes of lightning apparatus switching operations.
A word of caution.
