In this video, we provide a clear, step-by-step demonstration on how to measure soil resistivity and ground electrode resistance using a Digital Earth Tester. Whether you are an electrician, a site engineer, or a student, mastering this test is crucial for ensuring the safety and effectiveness of electrical grounding systems.
📋 What You’ll Learn
We cover the standard Fall-of-Potential method (3-terminal test), which is the most reliable way to verify that your earthing system meets safety standards.
Key Steps Covered:
* Preparation: Safely disconnecting the earth electrode from the main system.
* Probe Placement: How to properly space the Current (C) and Potential (P) spikes (the 5-10 meter rule).
* Connections: Wiring the Red (E), Yellow (P), and Red (C) leads to the tester.
* The Test: Operating the digital meter and interpreting the LCD readings.
* Validation: Understanding what a "good" resistance reading looks like based on local regulations (e.g., 5 ohms for most residential setups).
🛠️ Equipment Used
* Digital Earth Resistance Tester
* Two auxiliary ground spikes
* Three sets of color-coded test leads
* Hammer/Mallet for spike insertion
⚠️ Safety First
Always ensure the system is de-energized before disconnecting any earth bonds. Earth resistance testing should be performed during dry weather for the most accurate "worst-case" results.
