Surge Protective Devices (SPD) protects the electrical installation, which has wiring and accessories, consumer unit, wiring, and accessories, from harmful power surges or transient over voltages.
Surge protection device suppliers are working on these highly advanced surges to protect sensitive electronic equipment such as fridges, microwaves, computers, televisions, washing machines, and safety circuits. Hey, help to prevent overflows and have fire detection systems and emergency lighting. There are appliances with sensitive electronic circuitry in almost every house with can burn and get damaged due to power surges.
This article will help you out to answer all the necessary quires related the surge protection devices. Let’s find out.
When should a surge protector be installed?
When should surge protection be fitted? Most of the individuals do not have proper guidance regarding the fitting of the surges. These surges have a risk assessment that should be carried out to know whether you need it or not.
Why is it essential to use a surge protector?
A substantial fluctuation can damage any appliance with a microprocessor in voltage. A small power surge is not that harmful, but internally, it hurts the devices by having electronic rust. To prevent degradation of internal micro-processes on the electronic appliances, you need surge protectors.
Why is a surge protection device required in an installation?
protection against transient overvoltage is required where the consequence caused by overvoltage could:
- Cause in loss of human life, and serious injuries
- Result in damage to cultural heritage and interruption of public services
- Cause problems in commercial or industrial activities
- Affect a group of co-located individuals.
Types of surges device
Surge protection device supplier suggests three different types of Surge Protective Devices:
- Type 1 SPD fixed at the origin like the main distribution board.
- Type 2 SPD set at sub-distribution boards
- The combined Type 1 and 2 SPDs are fitted in consumer units.
- Type 3 SPD is provided close to the protected load.
Various devices protect the appliances, but the proper method is used to fit these devices. So, buy a reliable and suitable brand surge device so that it may not cause any problem and if you are installing it by yourself, take proper guidance that is there.
How does transient over voltages occur?
The human-made transients occur when the transformer and motor switch and there is some lighting. Previously, domestic installations were causing issues, but now advance new technologies are there to make your work much more accessible. They include electric vehicle charging, air or ground source heat pumps, and speed-controlled washing machines that are composed of transients much more likely to occur within domestic installations.
Moreover, the natural transient over voltages is caused by indirect lightning strikes. Most of the reason behind them is a direct lightning strike on an adjacent overhead power. There is damage to the electrical installation and associated appliances due to the telephone line. It is caused the transient overvoltage to travel along the lines.
