Surge Arrester
🔹 Introduction
Surge Arrester is one of the key equipment in electrical systems, whose main function is to protect equipment against transient voltages caused by lightning, momentary overvoltage, and electrical noise.
This device prevents damage to sensitive electronic and electrical equipment by directing excess voltage to the ground.
Surge arresters are used in the oil and gas industry, power plants, factories, telecommunication systems, and even building installations.
🔹 Features and Benefits
-
Protection of equipment against lightning and overvoltage
-
Increased safety of industrial and building electrical networks
-
Reduction of failure in sensitive equipment
-
Suitable for various applications from low voltage to high voltage
-
Compatibility with IEC and IEEE standards
🔹 Frequently Asked Questions (FAQ)
What is the use of surge arresters?
They are used to discharge transient voltages caused by lightning or network fluctuations to the ground.
What is the difference between low voltage and high voltage surge arresters?
The low voltage model is used in residential and building systems; the high voltage model is used in industrial power transmission and distribution networks.
Which brands produce the best surge arresters?
Reputable brands include ABB, Siemens, Schneider Electric, DEHN, and OBO Bettermann.
