What is the proper sequence for installing earthing on an overhead line?

2025-08-13

The correct sequence for installing and removing earthing devices is a strict safety protocol designed to protect the worker at every step. This process must always be performed using the proper live-line tools to maintain a safe working distance.

The correct sequence is:

  1. Test for Absence of Voltage: Before touching any part of the line, a voltage detector must be used to confirm that the line is de-energized.

  2. Connect to Earth First: The earthing device is first connected to a known earth point, such as the tower structure or a ground rod. This ensures the device is grounded before it touches the conductor.

  3. Connect to Conductor: Using an insulated hot stick, the other end of the earthing device is then connected to the conductor.

  4. Create an Equipotential Zone (EPZ): For maximum safety, earthing devices should be installed on all three phases, and the conductors should be bonded together. This creates an EPZ, ensuring all conductive components in the work area are at the same electrical potential.

Our portable earthing kits and insulated tools are specifically designed to be used in this sequence, providing the highest level of safety and reliability for linemen.
