Impressed voltage can often occur when HV & LV services, communication and data cables share the same service corridors, trenches or tunnels. Significant induced voltages and currents may be induced into the “victim” cable resulting in safety or mal-operation issues. Victim service operators may require reassurance that the parallelism will not cause hazardous conditions for their operatives or cause malfunction of their assets. Where induced currents and voltages exceed stated levels, a mitigation design is required.
