The application of new technology makes the ground resistance tester more effective. It abandons the traditional mode,Earth Resistance Tester adopts a new integrated circuit design, and uses the DC/AC conversion technology to combine the three-terminal button and four-terminal button measurement methods into one model,Earth Resistance Tester which is suitable for power, Railways, mines and other departments measure the grounding resistance of various circuit equipment; with the support of new technology,Earth Resistance Tester they can also measure soil resistivity and ground voltage.

The grounding resistance tester is used to measure the resistance value between the maintenance grounding end of various motors and equipment and the accessible metal shell. Insulation,Earth Resistance Tester absorption ratio,Earth Resistance Tester and polarization index experiments can be performed on power equipment to provide accurate pre-determination for series insulation experiments.

Since the charging current directly affects the insulation value test of a large-capacity test sample,Earth Resistance Tester a large charging current is required, and the stronger the charging ability,Earth Resistance Tester the closer the absorption ratio test value is to the true value. Product characteristics of grounding resistance tester:Earth Resistance Tester automatic analysis can be performed automatically, and data can be stored in sections for easy analysis; the output current is large, Earth Resistance Testerthe short-circuit current is greater than 5mA (when the battery is sufficiently charged); it is free from environmental interference,Earth Resistance Tester and can meet the site of ultra-high voltage substations operating;

DC power supply, with a high-capacity rechargeable battery included,Earth Resistance Tester which can work continuously for more than 6 hours on a single charge; the battery can be maintained by itself to extend the mission,Earth Resistance Tester if the instrument stops measuring, it can be actively shut down after about 2 minutes; the anti-shock design can effectively protect the instrument It is not damaged in the measurement;Earth Resistance Tester it can be discharged quickly to ensure personal safety during the measurement of large-capacity test samples; the test is allowed to be boosted before the test of the test sample,Earth Resistance Tester and can be measured continuously without turning off the power. In order to maintain its useful measurement effect,Earth Resistance Tester the storage environment temperature should be maintained at 0 ℃ ~ 40 ℃, the relative humidity should not exceed 80%,Earth Resistance Tester and there should be no corrosive gas in the air.
