Importance of surge protection device
A surge protection device is a device that plays an imperative role in limiting transient voltages by diverting the surge current. It’s capable of repeating the functions as specified. Surge protection devices were previously known as surge suppressors or secondary surge arrestors.
It’s a cost-effective solution for preventing downtime, improving the system, and data reliability to get the equipment protected from deteriorating due to surges and transients. This is typically used in various industrial, commercial, and residential places.
Types of surge protectors
Type1: This is connected for an installation between the service transformer and the line side of the overcurrent device equipment. The main purpose is to protect the insulation levels against external surges that are caused by the lightning and utility capacitors of bank switching.
Type2: This is permanently connected for installation on the disconnect overcurrent device including brand panel locations. The main purpose is to protect sensitive electronics against residual lightning energy and other internally generated surge events.
Type 3: Point of utilization surge protectors are installed with a minimum conductor length from the electrical service panel to the point of utilization. Examples include cord, direct plug-in, and receptacle type surge protection devices.
Well, surge protection devices provided by surge protection device supplier are commonly used for electric power supply networks, telephone networks, and automatic control buses. This is the primary and crucial component of the electrical installation protection system. This device is connected to the power supply circuit so that it can be protected and used at all levels of power. Below a shadow of any doubt, it’s a commonly used and efficient type of overvoltage protection.
Surge protection devices alleviate the voltages in:
- In common mode that’s between the neutral phase of earth.
- In a different mode, between phase and neutral.
Whenever the overvoltage exceeds the existing threshold, the surge protection device
- Conduct the overall energy to earth in common mode.
- Distributes the energy to other live conductors in a different mode.
