Power Cables: Operation, Maintenance, Location and Fault Detection - Live online course

Category: 
Electrical Engineering

THE COURSE

Faults in underground cables may cause loss of supply to customers and loss of revenue for suppliers so it is imperative that the fault location process is efficient and accurate to minimise excavation time, which results in reducing inconvenience to all concerned. For fault locating to be efficient and accurate technical staff need to have expert knowledge accompanied with experience in order to attain service reliability.

This course is designed to ensure that those responsible for the selection, laying, operation, maintenance and monitoring of power cables understands the technical issues involved and comply with relevant specifications and requirements.
