Hand-held three-phase zinc oxide arrester live tester/Zinc oxide arrester comprehensive tester
Product features:
Wired synchronization: The signal is taken from the PT end metering winding, and the digital signal is transmitted wired.
Wireless synchronization: Take signal from PT end metering winding, digital signal wireless transmission induction board synchronization: do not need to take signal from PT terminal, install induction board from zinc oxide arrester B phase base to take voltage signal.
No voltage synchronization: there is no need to take signals from the PT terminal, and the voltage reference is found by software calculation.
Voltage collector integrated local display and phase sequence detection function, can display three-phase full voltage, voltage fundamental wave, 3, 5, 7 harmonic RMS, system frequency value and three-phase voltage phase difference.
Bluetooth transmission function, automatically determine the connection status, the test result data can be transmitted to the background terminal through Bluetooth.
