Surge Protectors Are Classified Into Two Types: Shunt Type And Choke Type.

A surge protective device is a device used to protect power systems. Specifically, it prevents lightning strikes from damaging the power system during thunderstorms. Surge protectors are used to better prevent power system damage from lightning attacks. So, what are the main types of surge protectors based on their use?

1. Surge Protectors with Switches

During thunderstorms, a strong current can often cause varying degrees of damage to power equipment and facilities without any protective measures. Installing a surge protector with a switch will immediately close the switch when encountering such a strong current, preventing damage to the power system.

2. Surge Protectors with Voltage Limiting

When excessively high voltage or current enters the normal power system, the large external current intensity can cause damage, albeit to varying degrees. In such cases, surge protectors that can limit the external excessive voltage are needed.

3. Surge Protectors that Suppress Current

These surge protectors are generally divided into two types: shunt surge protectors and choke surge protectors. Different types are used in different situations. Generally, surge protectors should be used according to their structural principles and characteristics; blind operation should be avoided.

This concludes the basic introduction to surge protection device classification. The above classification is based on application; in addition, there are classifications based on performance and structure.
