ELECTRICAL SAFETY FOR STRINGING CONDUCTORS ON TRANSMISSION LINES
Serious electrical shocks have occurred during transmission line stringing activities in Australia over the last 20 years. Unfortunately, there are no standards or guidelines that adequately cover the electrical safety aspects associated with stringing. This talk discusses and explains the electrical hazards associated with stringing, including magnetic and electric induction, transferred potential rise, direct contact and lightning. Physiological effects of electric shock are discussed and options for derivation of electrical safety limits are presented. Basic electrical safety precautions are recommended along with a process for risk assessment. More detailed mitigation measures, training and administration of control measures are also presented. Recommendations on equipment used for earthing are also put forward.

Electrical Safety for Stringing Conductors on Transmission Lines
Tony Gillespie has 30+ years electricity supply industry experience of maintenance, operation and design of transmission lines and substations with Powerlink and its predecessors in Queensland. He left Powerlink in June 2010 and is now an independent specialist consultant in the area of electrical power systems.
His line design experience includes electrical design, specification and technical advice during construction for 1400km of 110, 132, 275 and 330kV HVAC transmission lines in Queensland, most with OPGW and composite insulation. Tony serves on many National Committees and is currently Convenor of electrical working group of Australian Standards EL 52 that has produced an Australian/New Zealand Standard AS/NZS7000 and accompanying Handbook H331 on transmission and distribution line design.
This replaces industry guideline ENA C(b) 1. Tony is a Fellow of Engineers Australia. Tony has written 32 technical papers and is a co-authored three Transmission line reference books published by EPRI.
