Surge protection devices are typically employed to secure the electronics system configuration, which comprises a unit called consumer, wiring, and accessories; from an electrical power perspective, transient overvoltages come into being.
This equipment is being used to ensure the protection of sensitive electronic devices during the installation of the communicating device, which includes computers, televisions, washing machines, and potential circuits, also incorporates some fire detection systems and Emergency Lighting. Electronic circuitry consists of sensitive equipment that can be vulnerable to impairment with the help of transient overcurrent.
What are TVS - Surge Protection Devices (SPDs)?
The results of a surge can be either an immediate failure or equipment damage that becomes apparent over time. Although other types of SPD are available to protect the installation from other incoming services, such as telephone lines and cable TV, SPDs are typically put within the Consumer Unit to safeguard the electrical installation. It is important to bear in mind that by only protecting the electrical installation and not the other services, transient voltages may find another way into the system.
The Most Used Three Different Types of Surge Protective Devices
- A Type 1 SPD is configured at the start of the application, e.g., the main distribution board.
- Type 2 SPDs are configured at sub-distribution boards (Type 1 & 2 SPDs are available and are usually installed in consumer units).
- Type 3 SPD is configured close to the protected load. They are primarily only installed as an addition to Type 2 SPD.
How Do Transient Overvoltages Function?
The switching of motors and Transformers, as well as various types of lighting, causes man-made transients to arise. Since the introduction of the new With technologies like air/ground source heat pumps, electric vehicle charging stations, and speed-controlled washing machines, transients have become considerably more likely to occur in home installations. Historically, this has not been a problem.
