Principle
|
The zinc oxide varistor installed within arresters, it has excellent nonlinear volt-ampere characteristic. In normal operating voltage, it displays large resistance, its leakage current is only microampere grade. While over-voltage appear, it translates low resistance immediately, releases energy and limits over-voltage range, it resumes large resistanceimmediately after over-voltage disappear, and ensures electric power system running safely. |
