MEYB-201SZinc oxide lightning arrester live testersolve了6-35kVZinc oxide lightning arresterThe difficulty of on-site live testing.6-35kVThe lower end of zinc oxide lightning arresters generally does not have a counter. Traditional testing instruments cannot sample current when live on site, and can only remove the lightning arrester from the circuit during major repairs and bring it back to the laboratory for testing, which is time-consuming, labor-intensive, and inefficient.MEYB-201SRealized online non-stop testing of zinc oxide lightning arrester! No need to climb poles, no need for wiring, fast and accurate testing!

MEYB-201SZinc oxide lightning arrester live testerSuitable for voltage levels6kV-500kVMultiple sampling methods are available for selection. When the lower end of the zinc oxide lightning arrester is equipped with a counter, the current signal can be sampled from both ends of the zinc oxide lightning arrester with the counter; Otherwise, wireless current clamps can be used for sampling. When there is a zinc oxide lightning arrester nearbyPTEquipment, voltage signals can be obtained fromPTSecondary voltage sampling, otherwise no voltage mode software simulation can be selected.

Zinc oxide lightning arrester is an important protective facility for power supply lines and equipment. If the lightning arrester ages, is damaged or fails in the power system, it may cause large-scale faults, resulting in damage to power equipment and power outages. Dealing with faults requires a significant investment of manpower and resources. Therefore, regular testing of zinc oxide lightning arresters in power lines can effectively eliminate potential safety hazards, ensure the safe operation of the power system, and improve the quality of power supply.

MEYB-201SZinc oxide lightning arrester live testerIt is an instrument used to test the electrical performance of zinc oxide lightning arresters, suitable for live or power-off detection of zinc oxide lightning arresters of various voltage levels, so as to timely detect dangerous defects such as insulation moisture and valve plate aging inside the equipment.
