Zinc Oxide Surge Lightning Arrester Test Zinc Oxide Surge Arrester Tester
Product Introduction:
Zinc oxide lightning arrester charged tester is used to test the electrical performance of zinc oxide lightning arrester special instrument, the instrument is suitable for various voltage levels of zinc oxide lightning arrester charged or blackout test, so as to timely discover the equipment internal insulation moisture and valve aging and other dangerous defects.
Main Product Features:
1. large wireless distance: compatible with wireless synchronisation, wireless transmission signal is more than 1500m, optional can reach 5000m.
2. synchronisation: support 485 wired synchronisation, wireless synchronisation; no voltage mode through the software calculation to find the voltage reference three synchronisation methods.
3. charged blackout compatible: suitable for lightning arrester charged, blackout or test room and other places to use.
4. a large number of range acquisition: voltage acquisition range 0-250V, current acquisition 0-20mA.
5. three-phase same test: truly three-phase current, three-phase voltage test at the same time, improve work efficiency; at the same time support single-phase test or two-phase test, convenient choice.
6. optional voltage mode: support to take three-phase or B-phase voltage reference as voltage reference; support to take B-phase electric field intensity as voltage reference by inductive plate (optional), this function is convenient for voltage sampling.
7. current mode optional: can be connected to the lightning arrester counter with a line at both ends of the sampling leakage current, you can also use the current clamp to collect the lightning arrester grounding line leakage current (optional).
8. standard side with anti-interference processing: with anti-interference calculation function and angle compensation function, completely solve the case of three-phase mutual interference 220KV and above the voltage level needs.
