A surge protection device is an electronic appliance that protects electrical devices from various voltage spikes. That is responsible for limiting the voltage that’s supplied to an electronic device by blocking or shorting the unwanted current.
This transient is most commonly used for describing the electrical devices that are installed in power distribution panels, process control systems, communication systems, and heavy-duty industrial systems for the protection of devices against electrical surges and spikes. The scaled-down versions of these devices are often involved in residential surface panels for the protection of household from hazards.
All types of surge protectors aren’t created similarly. They tremendously differ in terms of price and performance. Clamping voltage and energy absorption are the things to consider whenever picking up the premium-quality surge protector from the surge protection device supplier.
How to choose the right surge protection device?
Choosing the correct surge device usually involves a right surge arrester and protective circuit breakers. It has a wide range of parameters that are related to arrangements and assessments of devices.
Rules of thumb for choosing and installing surge protectors:
Since we all know surge protection devices are at the heart of a lightning protection system, then it’s time to think about how to choose the right surge protection device.
- Familiarize yourself with the types and qualities of surge protection devices.
- Assess the risk of lightning strikes and discharging capabilities.
- Use devices for the protection of surge arresters themselves.
Type1: Ensure to install the switchboards in buildings with various lighting protection systems. A wide range of powerful lighting currents can be easily discharged. It should be used as a lightning protection system where lightning roads and cages are installed.
Type2: Install the main power distribution switchboard that plays an integral role in discharging currents from lightning strikes and conductive/inductive overvoltages and transients. It should always be used.
Type3: This is dedicated to the protection of several devices. It has a low discharge capacity. It is used in the combination of industrial facilities where a lightning protection system is always in place.
However, for the protection of the switchboard, you only need to install a type 2 arrester with the discharge capacity.
How to protect your surge protection devices?
The thermal runaway that’s caused by the excessive constraints of the surge protection device needs to have slow destruction of internal components. The disconnection of the surge protection device provided by a thermal fuse is often associated with electronic components inside the surge protection device.
A short circuit due to the maximum circuit flow is protected by the surge protection device like a circuit or fuse breaker. There is a possibility that you might have to choose an external circuit breaker.
The circuit breaker is usually chosen as a short circuit current in the building that where the surge protection device is installed. So a disconnection circuit breaker has a current of 6Ka that’s ideally suitable for residential building. Whereas for an office it’s usually 15Ka or 20Ka.
