Lightning rods are enough to protect my building and my equipment
True and False. Electrical contractors, Batterham’s Electrical Switchboard Services and Trading, BESST Engineering, Queensland say that it is true that lightning rods do protect buildings in case fires are caused by a lightning strike. But they do not provide any protection against voltage surge caused due to massive amounts of energy generated during lightning. The electrical systems installation is generally below the ground. The lightning rod conducts current into the ground. Some of it may flow back into your circuits and damage your equipment. For protecting your equipment and appliances, you need surge diverters. BESST provides Gatekeeper surge diverters provides protection against surge voltages and surge currents caused by lightning.
No lightning, no surge, right?
False. Any power disturbances can create transients or spikes. While lightning does cause massive surges, a voltage surge can also be caused by devices that switch power on and off, like an appliance’s thermostat switch. Your area’s grid switching electrical loads can also cause a surge that is enough to kill your sensitive equipment since most of it is designed to operate only at a specified voltage.
My devices are plugged into a power strip. That is good.
False. Power strips are only a way to increase power points on a single outlet. They may save you from a fight about who gets to charge their phone first but they offer no real protection from a power surge. They are as good as plugging directly into the outlet. Only surge protection devices can protect your appliances and equipment against a voltage surge.
i have a surge protector. I am 100 percent safe now.
Depends. Choosing the right surge protection device and correct installation is paramount. Residential and industrial electrical contractors, BESST at Queensland advise that you get expert help to install a surge diverter or arrester. Length of the cable that connects the surge protection device to the mains is a critical parameter among many others like where the building is located, what is the risk level, what is the earthing mechanism and so on. Only experienced engineers and electrical contractors have the necessary knowhow to judge which surge device is right for you and how it should be installed.
Every time there is a surge, the surge diverter is destroyed and needs to be replaced.
False. Surge arresters discharge the excess energy to the ground each time it happens. And they can do it repeatedly. The life of a SPD (surge protection device) is as good as any other protection device. Gatekeeper surge diverters from electrical contractors, BESST Engineering, Brisbane are suitable for installation at the entrance of a building, in the main switchboard or a distribution board. Multiple surge diverters may be used to provide coordinated protection.
