KDYZ-201 Zinc Oxide Surge Arrester Live Tester is a specialized instrument used to test the electrical performance of zinc oxide surge arresters. This instrument is suitable for live or power-off detection of zinc oxide surge arresters of various voltage levels, so as to timely detect dangerous defects such as insulation moisture and valve plate aging inside the equipment.

The instrument is simple to operate and easy to use. The measurement process is controlled by a microcomputer and can measure the current, resistive current and its harmonics, power frequency reference voltage and its harmonics, active power and phase difference of zinc oxide lightning arrester. The large screen can display the real waveforms of voltage and current. The instrument uses digital waveform analysis technology and anti-interference methods such as harmonic analysis and digital filtering software to ensure accurate and stable measurement results. It can accurately analyze the content of fundamental waves and 3-7th harmonics, and overcome the influence of phase to phase interference to correctly measure the resistive current of edge phase lightning arresters.

1. The standard configuration of the instrument does not come with a high-efficiency lithium-ion battery, and can be optionally equipped with a built-in one.

2. 5.7-inch 320 × 240 LCD display, high-speed thermal printer; Graphic and textual display, intuitive interface, easy for on-site personnel to operate and use.

3. Suitable for use in places with live lightning arresters, power outages, or laboratories.

4. Isolation of current and voltage sensors, safe and reliable. Testing A, B, and C three-phase zinc oxide lightning arresters in three stages can be saved as one set of test data.

5. The instrument can perform continuous testing, display voltage and current curves, and quickly print data and curves.

6. Internally configured memory, capable of storing 200 sets of test data in case of power failure.

7. Optional RS232 communication interface, which can be used for testing and exporting test data through the upper computer.

8. Can perform anti-interference calculations to compensate for the deviation of phase A and C currents caused by phase B.

9. High speed sampling frequency, advanced digital signal processing technology, strong anti-interference performance, and high measurement accuracy.
