Understanding the Basics of Earth Testing
Grounding systems are critical for safety in any electrical installation. They provide a path for fault currents to safely dissipate into the earth, which protects equipment and reduces the risk of electric shock. An earth tester helps in assessing the efficiency of grounding systems by measuring their resistance.
What Does an Earth Tester Do?
The primary function of an earth tester is to determine the resistivity of the ground at the installation site. This information is essential for ensuring that grounded systems are functioning correctly. A low resistance value indicates a good connection to the ground, while high resistance signals potential issues that need to be addressed.
