UNDERSTANDING WHAT POWER SURGES ARE AND WHAT CAUSES THEM

The Unseen Risks Power surges can occur when the flow of electricity in the grid gets interrupted in some way. It can also happen when devices that are expected to draw electricity put them back into the circuitry instead. In Australia, the mains voltage operates at 240 volts and 50 Hz, many other countries such as Japan and the US have appliances that use 110V 60Hz etc. If you plug any such device into power outlets in your home without proper protection, it can result in a power surge causing extensive damage to the device. Harnessing electrical energy is not an easy task. Whenever all of these other aspects come into the picture, power surges can be dangerous. While there are no significant dangers in using electricity on a day-to-day basis, there are certain risk factors you need to keep in view at all times.

What Is The Duration Of A Power Surge? Whenever there is a sudden spike in the electrical current, it is less than a thousandth of a second, which is very quick. But the surge in the voltage can vary between hundreds and thousands of volts. You must know that voltage oscillates and there is never any fixed current that it runs at. While oscillation is part and parcel of how an electrical current would behave, whenever there are things like three-phase power etc. added to the mix, it becomes more complicated. This type of power creates different electrical phases within the alternating current. Since every country follows specific standards, electrical devices are manufactured to varying quality levels. All of these aspects have a role to play when it comes to power surges on your property.

Power Surges – The Common Causes

Various elements can cause power surges, and many of these are within our control, such as:

  • A high power electrical device can cause a sudden spike in power when you switch it on. Sometimes, this can happen when a high energy component like powerful motors kick-in. The sudden action can impact electrical devices on your property such as air conditioners, space heaters, refrigerators and more.

  • A tripped circuit breaker can still protect your home. However, if it has become damaged in doing so, that can prove to be a risk later on, and you would have to replace it.
