Tianji Lightning Arrester
Operating Principle
The metal oxide arrester(MOA) provides the most advanced protection against over-voltage in the world, since MOA resistors are made up of Zinc Oxide films, MOA has a good voltage-ampere characteristics compared with silicon carbide arrester, its 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 provides excellent protection for the HV equipment, especially the transformers, cables and switchgear.
Applied in power distribution network system, substation & transformer protection.
