Operating Principle

The metal oxide arrester provides the most advanced protection against over-voltage in the world, since MOA's resistors are made up of Zinc Oxide films. MOA has good voltage-ampere characteristics as compared with silicon carbide arrester, it is Volt-Ampere characteristics is much superior and results in much better performance.

A micro ampere level current flows while MOA is operating under normal voltage, but the amount of the current will be thousands amperes when MOA is subjected to over-voltage, because of MOA has a good non-linear characteristics. Hence MOA provide excellent prection for the HV equipment, especially the transformers, cables and switchgear.

Application

The metal oxide arrester which applies to protect the power equipment like transformers against system overvoltages and lightning surges.
