What is the primary function of a surge arrester? +
A surge arrester protects electrical equipment by limiting transient overvoltage’s caused by lightning strikes or switching operations and safely diverting surge current to ground, preventing insulation failure and equipment damage.
How does a metal oxide surge arrester work? +
Metal oxide surge arresters use non-linear MOV blocks that remain highly resistive at normal operating voltage and become conductive during overvoltage conditions, clamping the voltage to a safe level within nanoseconds.
Where should surge arresters be installed for maximum protection? +
Surge arresters should be installed as close as possible to the equipment being protected, such as transformers, switchgear, cable terminations, or panel boards, with a low-impedance grounding connection.
What is the difference between station class, intermediate class, and distribution class arresters? +
Station class arresters are used in substations and EHV/HV systems, intermediate class arresters serve MV networks, and distribution (secondary) class arresters protect distribution transformers and low-voltage equipment.
How is the correct surge arrester voltage rating selected? +
The voltage rating is selected based on the system’s nominal voltage, maximum continuous operating voltage (MCOV), grounding method, and expected surge conditions to ensure reliable protection without nuisance operation.
Do surge arresters require regular maintenance? +
Modern gapless MOV surge arresters are generally maintenance-free. Periodic visual inspection and monitoring of indicators or remote signals (if provided) are recommended to ensure continued protection.
What happens when a surge arrester reaches end-of-life? +
At end-of-life, the arrester may activate a thermal disconnector or show a visual/remote alarm indication, allowing safe isolation and replacement without causing system faults or equipment damage.
Are surge arresters suitable for outdoor and harsh environments? +
Yes. Integrated Power & Engineering surge arresters are designed with weather-resistant polymer or porcelain housings, offering high performance in outdoor, polluted, coastal, and high-humidity environments.
