1. Overview of the power test procedures.

A series of insulation performance tests are required for numerous power equipment such as cables, motors, generators, transformers, mutual inductors, high-voltage switches, arresters, etc. The first step is to conduct insulation resistance tests. In recent years, with the rapid development of the electric power industry, the use of large-capacity equipment has continued to increase, and it is impossible to detect its insulation performance with an ordinary megger.

Main technical indicators

1. Output voltage: -DC250V, -DC500V, -DC1000V, -DC2500V, -DC5000V Error: ±5% FS (FS is the full-scale value); Meet the requirements for fast charging of capacitive loads. Short-circuit current 5mA, automatic absorption ratio, Polarization index calculation, automatic rapid discharge function, and residual voltage display

2. Functional parameters: Automatic range conversion, convenient reading.Resistance display range: 0Ω to 500GΩ 250V, 500V, 0-5G 1000V, 0-20G, 2500V, 0-500G, 5000V, 0-10T, simulation progress bar displays 0- 10T capacitor discharge: from 5000 V to 50 V, <250 ms/μF discharge protection level: IP65 (cover closed), IP40 (cover open) Safety: meets IEC61010-1, CATIV600 V requirements

3. Resistance test accuracy range 1 M～10MΩ error: ±5%FS (FS is the full scale value); 10M～10GΩ error: ±3%FS (FS is the full scale value); 10G～100GΩ error: ±5%FS (FS is the full-scale value); 100G~500GΩ error: ±10% FS (FS is the full-scale value);

4. Voltage test function, automatic discharge function

5. After the instrument is tested, it automatically detects the residual voltage and automatically discharges,

6. Protect equipment and personal safety.

7. DC voltage test: 600V

8. AC voltage test: 600V

5: Other functions

1) Automatic timing function (maximum timing 600S), the instrument buzzer beeps once every second, and once every 15 seconds.

2) Automatically measure, calculate and display the absorption ratio and polarization index values ​​of R15S, R60S and R600S.

3) Enter the system menu to view records, modify time, short-circuit current, and filter settings.

4) Strong anti-interference ability, stable and reliable readings.

5) Complete protection functions to ensure safe operation.

6. Operating conditions Ambient temperature: 0℃-40℃ Relative humidity: ≤70%RH

7. Power supply range AC: 220V±10% Charging (built-in large-capacity lithium battery, AC and DC dual-use, portable) Automatically shut down when the battery power is low .

8. Volume and weight Volume: 280mm×210mm×100mm; Weight: <5kg
