Induced voltage in cable trays

Home / Induced voltage in cable trays

In some trays, tens of wires lie in direct contact with high amperage flowing through them. The result is a tray full of expanding and collapsing magnetic fields in the vicinity of current-carrying conductors. This Technical Brochure describes the induction phenomena (inductive, capacitive and conductive) that can lead to presence of voltage and currents on disconnected cable systems. It is aimed at pro- ject managers or subproject managers working on Energinet's construction projects. Shielded cables use the shield to "drain" away any induced or transient voltages.
