What is surge protection ?
Did you know that modern circuit breakers and surge protection are your first line of defence against fires and electrical faults.
Surge protection helps to keep your home or business protected from transient voltages.
A transient voltage is caused by the sudden release of stored energy, this can be due to lightening strikes, unfiltered electrical equipment, arcing, a capacitor bank or a generator being switched on or off. It causes abrupt changes in voltage and current conditions. These changes occur for a limited duration, usually microseconds or milliseconds but can have a profound effect on your electrical installation.
Hundreds of electrical transients occurr internally in power systrms everyday, due to switching operations of inductive loads, a blown fuse interupting a short circuit current is another example of an electrical transient that can affect your sensetive equipment.
A transient voltage may not cause damage straight away but over time unprotected equipment will get damaged.
How do we protect against these pesky transients ?
Surge protection devices (SPDs) are the most effective way to protect sensitive or vulnerable electrical systems.
The type of surge protector that we usually fit is a type 2 or type 3 , these protect against indirect ligthning strikes, switching transients, and transient over voltage.
This type of device acts like a pressure relief valve, absorbing and diverting excess voltage to ground during a surge event.
So when its time to upgrade or consumer unit, or you have recently had a new one installed and would like to have surge protection fitted, or you are not sure if your electrics are up to scratch? Give us a call for a quick chat or to book a safety check. Your peace of mind is worth it.
