Insulated boots and gloves are essential safety protective equipment for power system operation and maintenance. DL408 "Safety Work Regulations for Electric Power" specifies the testing methods and cycles for commonly used safety tools such as insulated boots and gloves. The voltage withstand test for insulated boots and gloves shall be conducted every six months, during which no breakdown is allowed, and the leakage current of the insulated boots shall not exceed the limit value.

The instrument adopts patented technology for multi-channel high-voltage leakage measurement and infrared data communication technology, achieving the goal of safe measurement of high-voltage leakage current. Through the application of this technology, the tester is completely isolated from the high-voltage system, which not only accurately measures multiple high-voltage leakage currents, but also ensures the personal safety of the testing personnel.

In order to improve work efficiency, 8 samples can be tested simultaneously at a time. To avoid repeated testing, high-voltage breaking patented technology is used. During the testing process, the punctured samples can be removed from the high-voltage testing system, and the non punctured samples can continue to be tested until the test is completed.

1. Simultaneously conduct a test on 8 insulated boots or gloves and measure the leakage current separately.

2. Adopting a large screen LCD display with full Chinese characters, it displays a large amount of information and simultaneously shows parameters such as 8 high-voltage leakage currents, test voltage, current, and timing time on one screen.

3. It can measure parameters such as test voltage and primary current of the test transformer.

4. Using patented infrared communication technology, the control panel is completely isolated from the high-voltage system to ensure the safety of the testing personnel.

5. Fully automatic voltage withstand test. After the experiment begins, the instrument automatically closes and boosts the voltage at the required speed according to the national standard. It starts timing and maintaining the test voltage when it reaches the predetermined voltage. When the time is up, it automatically drops to zero and cuts off the power. At the same time, it displays the leakage current of each test sample and automatically saves the test results.

6. Equipped with a dedicated grounding container for easy operation.

7. Each test sample is equipped with a high-voltage breaking mechanism. When any circuit breaks down, the test sample will automatically detach from the high voltage without affecting the progress of the test.
