Guidelines for safe work on cable systems under induced voltages or

BackgroundScopeContentInduced Voltage MechanismsPrinciples of Safe WorkConclusions and RecommendationsThis Technical Brochure presents and discusses several aspects of induced voltages on power cable systems. Three types of induced voltages have been considered; (i) - inductive coupling, (ii) - capacitive coupling and (iii) - conductive coupling (EPR). The focus of this Technical Brochure is on how to calculate induced voltages on the cable to be w...See more on electra.cigre IEEE Xplore
