General:

The Zinc Oxide Type Surge Arrester is the latest advanced over-voltage protector for distribution line and power station device. Incorporated with zinc oxide and other metal oxide as the core resistor disc, the volt-ampere characteristics and the through-current capability of the resistor discare improved drastically compared with the conventional SiC type surge arrester.

Under nominal operating voltage, the current through the surge arrester is only about micro-ampere grade. When the surge arrester experiences an over-voltage, the resistor disc with excellent non-linear characteristics will increase the current through the surge arrester to several thousand amperes instantaneously. The surge arrester is in a conducting state and then will release the over-voltage energy to the earth and thereby protects power distribution I transmission device against the impact of over-voltage.
