Schematic Surge Protector Circuit

As we all know sudden mains domestic voltage fluctuations are quite inevitable and can induce serious harm to our household electrical appliances.

Schematic surge protector circuit. This design a simple circuit protection that helps protect equipment from damage caused by transient surge voltages such as from lightning strikes and equipment switching operations. Surge protection circuit for power supplies eleccircuit com back lightning protector using gas discharge gdt edn a simplification ac supply how to use esd devices disk varistors tech schematics build homemade mains device bright hub arresters telephone line eeweb community practical tips installing in low surge protection circuit for power supplies eleccircuit com power back surge protection. A word of caution. 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 simple circuit idea of a mains surge protector unit has been explained in this article. I want to evolve this to a 350w 8ohm design. The circuit once built and installed in your house will assure a total safety to the various connected appliances from all possible sudden voltage triggers. The circuit diagram of a surge protector is shown below.

The design uses 2sc5200 output devices and tip41c drivers. Surge protection circuit is the one referred by many as protector for voltage spikes in ac grid lines. A wiring diagram is a simplified traditional photographic representation of an electrical circuit. This is a surge protector.

The device uses gas discharge tube gdt of te connectivity that effectively switches to a low impedance state and diverts the energy away from the equipment when an overvoltage is detected. 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. Surge protection circuit principle and design. However it is not limited particularly in ac grid lines.

The circuit of a simple ac mains surge protector device below. 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.
