It has been shown earlier 121 that Ultra Wide Band (UWB) transients can travel in differential mode (DM) along low voltage power installation cables, and deliver large amounts of power to connected equipments. However, branches in the network were not included at that time. In this paper, the ability of UWB transients to propagate through different types of junctions of low voltage power cables is investigated. The received voltage could with very good accuracy be estimated from Transmission Line Theory, either using theoretical calculations or numerical simulations. This was verified experimentally. The decrease in voltage received at the loads of the branches is mainly due to the reflection caused by impedance mismatch at the junction. It is concluded that large voltages can be delivered to unprotected loads, if a UWB transient is injected in DM at another part of the same network.
