Surges can cause significant damage to sensitive equipment, including computers, telecommunication devices, and other electronic appliances.

How Surge Arresters Protect Against Electrical Surges

Surge arresters are instrumental in safeguarding electrical systems by redirecting excessive electrical energy away from connected equipment. When a surge occurs, the arrester immediately detects the overvoltage and forms a low-resistance path for the excess current to be safely conducted to the earth, thus preventing it from reaching the sensitive devices. This protective mechanism ensures that equipment remains safely operational and minimizes the risk of damage or disruption.

Components Of A Surge Arrester

Understanding the components of a surge arrester is vital to recognizing its inner workings. These devices are typically composed of several essential components working together to provide effective surge protection. Let’s take a closer look:

Component Function
Metal Oxide Varistors (MOVs) MOVs are the heart of surge arresters and are responsible for absorbing and dissipating the surge energy, effectively limiting the voltage that reaches the connected equipment.
Porcelain or Polymer Housing The housing encapsulates the surge arrester’s components, protecting them from environmental elements such as moisture, dust, and temperature variations.
Gaps and Sparkover Voltage Gaps within the surge arrester, along with their specified sparkover voltage, determine at what voltage the arrester activates, providing the necessary diversion of the surge current.
Arcing Chamber The arcing chamber is responsible for interrupting the surge current once it has been diverted, preventing it from continuing to flow through the arrester.
Grounding Connections Proper Grounding Connections ensure that the excess current finds a safe path to the earth, protecting the electrical system and the connected equipment.

By ensuring that all these components are in optimal condition, surge arresters can effectively carry out their duty of protecting your electrical systems from voltage surges.
