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 a 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 protection for the HV equipment, especially the transformers, cables and switchgear.
