Surge Arresters Testing
Surge arresters play a critical role in safeguarding electrical equipment and systems from transient overvoltages caused by lightning strikes or switching operations. At SLPL, our Surge Arresters Testing services ensure that your systems remain protected and reliable under all operating conditions.
What is Surge Arresters Testing?
Surge arresters, also known as lightning arresters, are devices installed in electrical networks to divert excessive voltage to the ground, thereby protecting critical components such as transformers, switchgears, and substations. Over time, surge arresters may deteriorate due to repeated surges, environmental exposure, or aging—necessitating routine diagnostic testing.
SLPL offers comprehensive surge arrester testing to evaluate condition, performance, and remaining service life—ensuring safe, uninterrupted operation of your power systems.
