3. **Check for Missing Earthing Tape/Strip**
Conduct a thorough inspection for any missing earthing tape or strip across its span.
4. **Measure Earthing Resistance**
Test the earthing resistance using an earth tester to ensure it meets the required standards.
5. **Review Historical Reports and Compliance**
Review previous earthing test reports and the original earth mesh design, checking compliance with **IEEE-80 standards**.
6. **Soil Resistivity Measurement**
Measure the soil resistivity to determine if additional electrodes are required for enhancing the earthing system.
7. **Verify Equipment Connection**
