ARRESTERS Meaning and
Definition
-
Arresters are devices used in electrical and electronic systems to protect against overvoltage by diverting excessive electrical energy to the ground. Also known as surge arresters or lightning arresters, they are designed to safeguard equipment from the damaging effects of voltage surges, such as those caused by lightning strikes, switching operations, or malfunctions in the power grid.
Arresters consist of multiple components housed within a protective enclosure. The main element is a non-linear voltage-dependent resistor, typically made of metal oxide varistors (MOVs) or silicon carbide (SIC). When the voltage across the arrester exceeds a certain threshold, the resistor conducts, providing a low-resistance path to ground. By absorbing the excess energy, the arrester prevents it from propagating to sensitive equipment, thus limiting voltage transients to a safe level.
These devices are commonly used in electrical substations, power transmission lines, distribution networks, and telecommunication systems. They are vital to protect essential equipment, such as transformers, circuit breakers, insulation, and control systems, from damage or failure.
Arresters are categorized based on their voltage rating and application, with options available for low, medium, and high voltage systems. They are designed to provide reliable protection, have a long service life, and exhibit low leakage current under normal operating conditions.
Regular inspection and maintenance are important to ensure their continued effectiveness. In case of any damage or insulation breakdown, it is crucial to replace arresters promptly to maintain optimal system protection.

Etymology of ARRESTERS
The word "arresters" is derived from the verb "arrest".
The word "arrest" originated from the Middle English "aresten" or "arresten", which came from the Old French "arester". In turn, the Old French "arester" was derived from the Latin "ad-" (meaning "to") and "restare" (meaning "to stop, resist").
Therefore, the etymology of "arresters" can be traced back to the Latin "adrestare", meaning "to stop, seize" which eventually evolved into the Old French and Middle English forms. "Arresters" refer to multiple objects or devices used to stop or prevent something, most commonly used in the context of electrical surge arresters, which are devices designed to protect electrical systems from voltage surges.
