All You Need to Know About Surge Protective Devices!

Surge protective devices are very impact in keeping your electrical equipment safe against sudden surge of power loads. Here’s all that you need to know before buying SPD for your home or office.

A surge protector is a device that is used to keep your electrical installation safe and secure. It provides an unassailable protection to your devices against the unexpected voltage spikes. Installed in your power supply circuit, it limits and controls the power load transferred to the electrical equipment when the voltages go above a safe level.

Surge protective devices are in huge demand nowadays. Most smart houses and companies have them installed, in a bid to keep their valuable electrical machines risk-free.  The surge protectors can be attached to one particular device or/and for the whole electrical supply circuit. They come in different sizes and designs, suitable for varied equipment and appliances. Their importance has grown higher than ever before. Simply because today’s electrical devices are very sensitive to power spikes. They can be damaged if the voltage suddenly goes above the safe level. To avoid this loss, you better have ASCO surge protective devices installed in your home/office.

Set in parallel on the power supply circuit of the loads, a surge protective device, SPD, features high impedance. When the system notices overvoltage, the impedance of SPD controls the loads and supply the right quality of power to the sensitive equipment.

SPD works on certain principles. It’s important to know these principles to understand the real essence of the device. An SPD is designed to control the transient voltage when it goes beyond a safe level. The current waves are diverted to earth to curb the magnitude of the sudden surge that can be hazardous for the electrical equipment and some time for the whole installation. The device comes with different live conductors to which the excess energy is distributed in various modes.

Different Types of SPD

The Type 1 Devices

These devices are highly effective to protect industrial buildings and houses from lightning strikes. They provide a much-needed support to your lightning protection system, with their ability to discharge the back-current from lightning. Type 1 SPD often comes with a 10/350 µs current wave.

The Type 2 SPD

Ideal for low voltage electrical installations, the Type 2 protector devices limit the overvoltage and prevent it to reach to the electrical equipment. These SPDs are installed in the electrical switchboard and are often characterized by a current wave of 8/20

The Type 3 SPD

These low discharge capacity surge protectors are commonly used as a supplement to Type 2 SPD and in the close proximity of the sensitive loads. Typically, these types of SPDs come with blend of 1.2/50 μs voltage waves and 8/20 μs current waves.

How to Buy SPD

You can buy surge protecting devices online. There are many reliable suppliers of automatic transfer switches and SPDs. One of them is ASCO Power, a company that has been relied upon by individual houses as well large organizations for supplying high-quality ASCO surge protective devices – all at reasonable prices. You can find a range of SPDs and ASCO ATS suitable for different electric installations.
