FAQs

Q1: What is a clamp-on earth resistance tester?
A1: The clamp-on earth resistance tester can measure the connection resistance of any looped system without using an auxiliary ground rod or interrupting the grounding of the equipment under test. As long as the ground wire or ground rod is clamped with the clamp head, the ground resistance can be measured safely and quickly. It can also be applied to multiple parallel grounding systems. The clamp-on ground resistance tester can measure the leakage current of 1MA, and the neutral line current can reach 20A. This function is especially important when the ground network to be tested contains large noise and harmonics.

Q2: How does a clamp ground resistance tester work?Earth resistance tester working principle
A2: The basic principle of the clamp ground resistance tester to measure the grounding resistance is to measure the loop resistance. The jaw part of the clamp meter consists of a voltage coil and a current coil. The voltage coil provides the excitation signal and induces a potential E on the loop under the test. Under the action of the potential E, a current I will be generated in the circuit under test. The clamp meter measures E and I, and the measured resistance R can be obtained by the following formula. The formula is R=E/I. This is how a clamp-on ground resistance tester works.

Q3: What is the earth resistance tester used for?
A3: The ground resistance tester can accurately measure the grounding impedance, grounding resistance and grounding reactance of large grounding grids.

  • It accurately measures the surface potential gradient in the large-scale grounding grid area.
  • Earth resistance tester can measure the contact potential difference, contact voltage, step potential difference and step voltage of large grounding grids.
  • Measure the transfer potential of large-scale grounding grids and soil resistivity accurately.
  • Digital earth resistance tester is used to measure the on-resistance of the grounding down-conductor.

Tips: What can a clamp earth resistance tester test?

  • It can test ground resistance (the grounding system that forms the loop), and the resolution is 0.0010.
  • The clamp earth resistance tester can accurately measure the loop resistance and the loop resistance.
  • Metal connection conduction (equipotential, based on loop), resolution 0.0010.
  • The clamp ground resistance tester can measure ground leakage, resolution 0.001mA (1uA) and AC leakage, resolution 0.001mA.
