Working design the circuit of a simple ac mains surge protector device below which shows how to make a simple homemade ac mains high current protector device is based on very simple principle of speed breaking the initial jolt through components who are well equipped in the field.
Surge protector circuit design.
However it is not limited particularly in ac grid lines.
This is a surge protector.
A tower style surge protector can help ensure the things you plug into it don t get in the way of one another and the bestek power strip tower is a phenomenal option.
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.
A simple circuit idea of a mains surge protector unit has been explained in this article.
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 surge protector definition is an electrical device that protects the computer system as well as various electronic devices from sudden voltages within electrical power otherwise transient voltage that supply from the power supply.
A word of caution.
In india the limit of standard voltage used for home office or buildings is 230 volts.
