Application
Metal Oxide Arrester (MOA) is the most advanced over-voltage protection. The core components using Zinc oxide barrier, compare with traditional silicon carbide arrester, it changed the characteristic of arrester, improve the flow capacity of over-voltage, so that make arrester changed fundamentally.
When the arrester working under nominal voltage, only Microamp current flowing through the arrester. When encountered lightning hit, because of the nonlinear of ZnO barrier, thousands of amps current flow through the arrester at that moment, arrester under conduction status, release over-voltage energy, effectively limits the violations of over-voltage on the transmission and distribution equipment.
Condition of Use
Ambient temperature: -40 degree - 40degree
Altitude: 1000-2000m
AC Frequency: 50Hz or 60Hz
Long-term working voltage applied to the arrester does not exceed the continuous operating voltage.
Maximum wind velocity: ≤ 35m/s
Earthquake class: ≤ 7°
Polluted areas should state.
Use characteristics
Metal oxide surge arresters use for protection of AC electrical power system, avoid from the atmosphere over-voltage and operating over-voltage damage.
