High Precision Zinc Oxide Test Set for Leakage Currents

Product Description

 

Product Description

1. This instrument can be widely used in equipment maintenance of substations and power plants, and to measure insulation resistance, absorption ratio and polarization index of high-voltage electrical equipment such as transformers, reactors, capacitors, and circuit breakers. The leakage current of the low-voltage arrester of the power distribution cabinet is automatically tested.

2. The instrument is controlled by a microcomputer and has a full Chinese operation interface. It can automatically complete the MOA test, the absorption ratio of the insulation resistance, and the polarization index test; it has functional options such as withstand voltage test and rapid test.

3. During the test and after the test is over, press the [↑] key to save the data; after each automatic test, if the test data is valid, the system will automatically save it.

4. The instrument has its own clock and temperature and humidity test functions, which can save 100 sets of MOA test data and 100 sets of insulation resistance test data.

5. The output power is large, and the short-circuit current is greater than 5mA, that is, the charging current to the load is 5mA.

6. The use of new circuit design and the introduction of digital filtering technology has strong anti-interference ability and is suitable for complex high-voltage field measurements.

7. Electromagnetic compatibility design, strong impact resistance, safety plastic case, easy to carry. Built-in large-capacity 2600mAh lithium battery. Intelligent charging circuit, long battery life.

8. With automatic discharge function after the test, there are voice and text information prompts during the discharge process. The time to discharge to 60V is less than 10 seconds.

9. Using 128*64 dot matrix graphic LCD display, with green backlight, not affected by light, making the reading clearer.

10. The meter will automatically shut down if there is no action for 10 minutes.
 

Measuring range and accuracy:

(when the measured resistance is less than 10MΩ, it is normal for the voltage to drop)
