Abstract

Working on powerlines is an inherently dangerous occupation. Powerline construction and maintenance can be performed whilst the power line is energised or de-energized. Although working with the powerline switched off is logically safer, a lineworker may still be exposed to lethal electrical hazards with causes such as lightning, induction or accidental energisation. Sadly, there are numerous examples where line workers have been electrocuted working on de-energised powerlines.

The title of this project is 'Prevention of electrical accidents with safe personal protective bonding and earthing'. Personal Protective Bonding and Earthing (PPBE) is a safety technique employed by line workers to protect themselves against the the risk of an electric shock. The technique aims to ensure the worksite is maintained at equipotential conditions at all times. This is attempted by the installation of bonding cables at or near the work area to ensure all conductive surfaces are electrically connected together.

The project aim is to identify unsafe conditions that may exist for the application of PPBE. If unsafe conditions are identified it may be possible to determine solutions
which will make working on powerlines safer.

The electrical principles which underpin the use of PPBE can be applied to all forms of electrical work. However, the focus of this project is on high voltage distribution
powerlines.
