Surge Arrester
How does surge arrester work?
A surge arrester works by diverting extra voltage to the ground, rather than flowing through electronics, while allowing normal voltage to continue along its path.
Characteristics of surge arresters
● Application: Protect various electrical equipment in the power system from damage caused by lightning overvoltage, operating overvoltage, power frequency overvoltage;
● Color: Red, Brown, Gray or Customer's requirement;
● Applicable Standard: IEC, GB, BS, ANSI, AS or Customer's requirement;
