Advanced Polymer Housed Metal-Oxide Surge Lighting Arrester

Operating principle
1. Metal-oxide surge arrester provides the most advanced protection against over-voltage in the world, since MOA’ resistors are made up of zinc oxide films.
2. MOA has a good voltage-ampere characteristics as compared with silicone carbide arrester, its volt/ampere characteristic is much superior and results in much better performance.
3. 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 transformer, cables and switchgear.

Application
Metal-oxide surge arrester which applies to protect the power equipment link transformers against system overvoltage and lighting surges.
