Grounding Resistance Tester (Earth Ground Tester)

Grounding Resistance Tester : (Earth Ground tester) When measuring earth resistance with an instrument, it is important to know some of its basic characteristics in order to accurately measure the soil resistance and to properly size the grounding installation. Most importantly, the range of resistance the device measures. Usually the range is three or four degrees. The soil moisture at which the appliance operates is another important parameter. If the instrument cannot operate at a certain humidity, then the measurement may differ significantly from the real value of soil resistance. Comparison analog and digital grounding resistance testers. The main characteristics.

The meter generates an electrical current and then supplies it to the measuring electrodes. The potential difference between the two electrodes gives information about the value of soil resistance.

Analog Grounding Resistance Tester: The analog grounding resistance tester is realized by four main blocks DC generator, rectifier, current and potential coil. The deflection of the pointer of the analog screen depends on the ratio of the voltage of pressure coil to the current of the current coil.

It is critical for facilities to have grounded electrical systems, so that in the event of a lightning strike or utility over voltage, current will find a safe path to earth. To ensure a reliable connection to earth, the International Electrical Testing Association specifies ground electrode testing every three years.

Fluke’s family of electrical earth ground testers have been built to address the entire spectrum of ground testing methods from the basic to the most advanced. Our testers have been designed to be accurate, safe and easy to use. We provide quick and precise resistance measurements through several test methods: 3- and 4-pole Fall-of-Potential testing, selective measurement testing, stakeless testing and 2-pole testing.
