The ROEP at a number of our sites exceeds 650 V (Hot Sites),
creating a possible transferred potential hazard to third parties in the
vicinity of the site, as a consequence of metallic services to
properties e.g. telephone, LVAC, gas, water etc.
The transferred potential hazard may result in personal injury and/or
damage to electrical equipment, in particular telecommunications
This project is propose to determine the hot zones and transferred
potentials in electrical installations and establishes better procedures
for a full risk assessment using probabilistic methods.
