DURATION: 6 Hours

COURSE DESCRIPTION: 

An earthing is an intentionally made connection between a device or electrical installation and a metal object located in the ground called an earth electrode. Grounds have several protection applications – for natural phenomena and to prevent damage to equipment and property.

In this training, the participants will be able to understand grounding and the related electrical test, methods, and analysis of results.

Part 1 – Introduction to Soil Resistivity

Part 2 – Soil Resistivity Testing (with some case studies)

Part 3 – Introduction to Ground and Ground Resistance Measurements

Part 4 – Grounding Nomograph

Part 5 – Ground Resistance Measurements (with some case studies)

  • Fall of Potential
  • Slope Method
  • Direct Method
  • Stake-less Method
  • Ground Grid Integrity Test
  • Step and Touch Voltage Measurements
