DC Resistance Tester: Key Tool for Detection and Maintenance

The DC Resistance Tester applies a stable DC current to the object under test, measures the resulting voltage drop, and calculates the resistance value according to Ohm's law (R = V/I). To ensure measurement accuracy, the tester typically provides multiple current levels for selection, allowing measurements on different types of conductors.

Switch Characteristic Tester is mainly used to measure the closing of high-voltage switchgear at 155bb

The switch characteristic tester is mainly used to measure the mechanical parameters of high-voltage switchgear during closing and opening operations, such as action time, travel, speed, bounce count, etc. By analyzing these parameters, the health status of the switchgear can be evaluated, and problems such as wear and aging can be detected early, avoiding power outages caused by switch failures.

118 Wuhan Wireless Caller Insulation Resistance Tester: An Essential Tool for Electrical Safety Testing

The working principle of the insulation resistance tester is based on Ohm's law. When the tester applies a known DC voltage (typically 50V, 100V, 250V, 500V, 1000V, etc.) across the tested object, if the object has good insulation performance, the current passing through is very small; conversely, if insulation is poor, a larger current will pass through. The tester measures this current and calculates the insulation resistance value according to the formula R = V/I.
