Using a non-contact measurement method, it only requires 1/10 of the measurement time compared to traditional methods, without the need for additional auxiliary electrode rods. The clamp-type ground resistance tester has the capability to measure leakage current in the grounding system and neutral line current. The clamp-type ground resistance tester is widely used in the measurement of ground resistance and circuit resistance in various fields such as power, telecommunications, meteorology, oil fields, construction, and industrial electrical equipment.
The hook-type ground resistance meter is an instrument used to measure the resistance of the ground or grounding system. Its working principle is based on Ohm's Law, which describes the relationship between current, voltage, and resistance. Specifically, the hook-type ground resistance meter measures the resistance of the grounding system by clamping or hooking onto a specific point on the object being measured and applying a known current through that point. _This type of instrument typically includes a hook-shaped fixture that allows for easy clamping onto the measurement object, such as a grounding rod or other conductor. The instrument then sends a known current through the fixture to the ground while simultaneously measuring the corresponding voltage. According to Ohm's Law, resistance can be calculated by the ratio of voltage to current, allowing this method to determine the resistance value of the grounding system. In addition, hook-type ground resistance meters are often designed for non-contact measurements, meaning that there is no need to directly connect the measuring instrument to the grounding object during the measurement process. This enhances safety and simplifies the operation. This method typically allows for measurements to be completed in a relatively short time without the need for additional auxiliary electrode rods.
