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 equipment.

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.
