How to calculate the electromagnetic interference generated from a 132kV single core (in trefoil formation) power cable, need to be calculated for diffrent distances, like 1m, 2m,5m.

Do to the scares information provided and the complexity of the subject, it is difficult to explain in detail in this forum how to calculate the EMI interference of the HV UG line.

However, we can advance that the conceptual solution involves the interdependence between electromagnetic interference (EMI), electromagnetic fields (EMF), and grounding methods of the UG line.

Electromagnetic fields, produced by the UG transmission lines, particularly under a fault scenario, could potentially generate uncontrolled electric “noises” such as induced voltages which can be a safety problem, distort communications, control signal cables, and even impact the integrity of pipelines. The EMI is a growing concern in the power utility and pipeline industry.

The best way to calculate the EMI is using computer programs available developed from EPRI, the American Gas Association (AGA)and possible by PTI. To not let you go with an “empty pocket”, below is a typical approximation of the EMF profile of the 132 kV UG cables in a trefoil configuration as requested.
