This tester is used to test the electrical performance of each phase of zinc oxide arrester (MOA).It aso belongs to lightning protection test meter.
This instrument is suitable for on-site live detection of zinc oxide arresters of various voltage levels, as well as factory and acceptance tests performed by the laboratory under power failure.
By measuring parameters such as full current and resistive current, dangerous defects such as dampness of the internal insulation of the zinc oxide arrester and aging of the valve can be found in time.
It can measure the electrical parameters of the three-phase zinc oxide arrester at the same time, and can automatically compensate for the inter-phase interference; it can also be single-phase measurement, support the B-phase grounded PT secondary voltage as the reference voltage; when the measured phase is different from the reference voltage , Can automatically calculate the compensation angle.
Provide wired and wireless testing methods, wireless testing methods are more convenient and flexible; it can greatly reduce the work intensity of field testers.
The unique induction board replaces the PT secondary voltage measurement technology, making the measurement safer and faster.
