The live-testing instrument for zinc oxide surge arresters is used to evaluate the electrical performance of each phase of a zinc oxide surge arrester (MOA). This instrument is suitable for on-site live testing of zinc oxide surge arresters across all voltage levels, as well as for factory and acceptance tests conducted in the laboratory under de-energized conditions. By measuring parameters such as total current and resistive current, it can promptly detect hazardous defects, including internal insulation moisture absorption and valve element aging, in zinc oxide surge arresters.

A high-performance, low-power ARM processor equipped with a DSP floating-point unit is employed, delivering faster computation speed, higher computational accuracy, and the ability to process larger volumes of data; thereby ensuring the accuracy and stability of test data calculations.
High-precision sampling filter circuits and digital filtering techniques can effectively eliminate on-site interference signals.
A floating-point fast Fourier transform algorithm is employed to achieve high-precision analysis of fundamental and harmonic voltage and current signals.
It features an industrial-grade 5.7-inch monochrome LCD display with a 320×240 dot matrix, providing clear visuals and a user-friendly human-machine interface. For critical operations and parameter settings, the system displays prompt messages and detailed help instructions. The status bar at the top of the screen shows the operating status of each peripheral device and test status information.
It can simultaneously measure the electrical parameters of three-phase zinc oxide surge arresters and automatically compensate for interphase interference; it also supports single-phase measurement, with the secondary voltage of the PT on phase B as the reference voltage. When the phase of the device under test differs from that of the reference voltage, the system automatically calculates the compensation angle.
Both wired and wireless testing methods are provided; the wireless method is simpler and more flexible to operate, significantly reducing the workload of field testers.
The voltage data collector integrates a local display (a 128×64 dot-matrix OLED LCD) and phase-sequence detection functionality, enabling it to display the three-phase full voltages, fundamental voltage, and the RMS values of the 3rd, 5th, and 7th harmonics, as well as the system frequency and the phase differences among the three-phase voltages. This facilitates quick verification by field test personnel of the connection between the voltage data collector and the PT secondary voltage output terminals, as well as the measurement of various three-phase voltage parameters.
The voltage collector employs dual all-digital isolation technology, enhancing safety and reliability.
Dual AC/DC operation: powered either by a built-in lithium battery or by a 220V AC charger, with automatic adaptation.
The instrument host and voltage collector are equipped with high-capacity, rechargeable lithium batteries that provide up to 8 hours of continuous operation on a single charge.
Intelligent power management: remaining battery level display, low-battery alert, long-idle reminder, and automatic backlight adjustment.
Built-in real-time clock that displays the current date and time; automatically records the test date and time.
Test data can be stored either locally on the device or on a USB flash drive. Local storage accommodates up to 100 test records and allows these records to be transferred to a USB flash drive. USB flash drive storage supports both test data and waveform images; the test data is saved in TXT format, while the waveform images are in BMP format, enabling direct editing and printing on a computer.
Built-in thermal printer for printing test data and saved test records; customizable print content to help reduce paper consumption.
