Product Description

Digital Grounding Resistance Meter Earth Ground Resistance Tester with Voltage Measurement Function


Definition

Earth Ground Resistance Tester used for measuring the resistance of the earth is known as earth tester. All the equipment of thepower system is connected to the earth through the earth electrode. The earth protects the equipment and personnel from the fault current. The resistance of the earth is very low. The fault current through the earth electrode passes to the earth. Thus, protects the system from damage.
 

Performance Characteristics

Compared with the traditional hand-operated ground resistance meter, this meter has the following features:
DC/AC conversion technology is applied, integrating three-end knob and four-end knob measurement methods, and the power supply can be used for both AC and DC.
Adopting phase-locked loop synchronized tracking detection method and switched capacitor filter, with strong anti-interference ability.
Abandon the traditional manual hand-cranking power generation method, no need to manually adjust the balance. The easy-to-read panel touch key operation and LCD digital display make the measurement very convenient and fast, eliminating the visual error of the pointer type meter.
Allowed auxiliary grounding resistance resistance value is large, better ensure the measurement accuracy, high resolution.
In addition to testing grounding resistance, it can also test low voltage conductor resistance value, soil resistivity and AC ground voltage.
