Ground resistance tester


Clamp ground resistance tester is used to measure the ground resistance of any loop system. The instrument itself can generate a power potential and can generate current in any loop system. Therefore, its measurement principle is simple, is a full circuit Ohm's law, it measures the loop resistance value of the loop system.


Clamp type grounding resistance tester is widely used in electric power, telecommunication, meteorological, oilfield, construction and industrial electrical equipment grounding resistance measurement, with long pliers and round pliers. Long jaws are especially suitable for flat steel grounding.


Field application of the ground resistance tester Measuring the ground resistance of the power system The ground of the transmission line tower usually constitutes a multi-point grounding system. The ground resistance of the branch can be measured by clamping the ground wire with ETCR series pliers.


Transformer neutral grounding resistance Measurement There are two cases of transformer neutral grounding: When the transformer is repeatedly grounded, a multi-point grounding system is formed. When the ground is not repeated, use a single point grounding measurement. During measurement, if the clamp meter reads L0.01Ω, there may be more than two ground wires connected to the same tower or transformer and connected underground. At this time, other ground leads should be unwound, leaving only one ground lead. Three. ETCR series clamp meter in power plant substation application, can test the contact and connection of the circuit. With the help of test lines, the connection between station equipment and ground network can be measured. Ground resistance can be measured at a single point.
