Surge protectors supplied by electrical companies in Melbourne are designed to protect appliances and electronic items from power surges and any other potentially damaging interference on power lines. Not everybody has one, but they are worth the investment, mainly if you live in an area that often has electric storms with lightning.

Reputable electrical companies in Melbourne stock good quality surge diverters that Precision Electrical and Plumbing can install into the main switchboard in your home, protecting all your electronic and electrical equipment.

What Is A Surge Diverter?

Surge diverters are electronic devices designed to protect appliances and other electrically powered devices from voltage or power spikes. They are programmed to do this by shorting unwanted voltages to the ground or blocking them from remaining at a safe threshold. They activate when the normal 240-volt power lines spike above 275 volts.

This could be happening without you even knowing it. Most appliances can take small spikes in voltage, but the appliance will fail prematurely if this happens regularly. The surge protector will sacrifice itself to save the electrical equipment within the house. The only maintenance is to check the surge diverter to see if it has been activated. If it has, it needs to be replaced, as your appliances are now unprotected.

Most of the time, when there aren’t any electrical surges, the surge protection device will not affect the electrical system. It is like an open circuit and maintains isolation between the earth and active electrical conductors. As soon as a voltage or power supply surge occurs, it can instantly reduce impedance and divert the impulse current. Then it becomes a closed-circuit, short-circuiting the excess voltage. As soon as the impulse surge is over, the device becomes an open circuit again.

Surge protection starts where the electrical system originates at the switchboard and can stop the electrical surge before it reaches your electronic and electric equipment that would otherwise be at risk of damage.

What A Surge Diverter Isn’t According To Electrical Companies In Melbourne

Surge diverters are not electrical safety switches, and they are not circuit breakers either. You will need one in addition to these other electrical items. A surge diverter is also not designed to protect your appliances and electric items from damage in the unlikely event of lightning struck by your house.

Contact Precision Electrical and Plumbing for more information and a quotation for installing a suitable surge diverter in your home. We will also ensure that the device we purchase from one of the leading electrical companies in Melbourne is compliant with Australian Standards.
