Test Fault Location for 33 & 69 KV Cables

Code : E/36

Why Attend This Training Course?

The introduction of cables with extruded dielectric insulation and of modern splicing technology has imposed new conditions and restrictions on cable fault locating. The use of excessive high voltages and energies during AC, DC and surge testing of service-aged power cable systems with extruded dielectric insulation may over stress insulation, creating defects which become faults after the cables are returned to service. The course is designed to provide troubleshooting and testing personnel with methods of quick, effective, accurate and safe fault location, thereby reducing system outages and minutes lost by introducing them to all typical methods for cable testing: cable and fault diagnosis, pre-location of cable faults, fault conditioning, and pinpointing  fault location using magnetic acoustic methods in order to minimize the  risk of further damaging serviceable cables, terminations, and equipment. Whenever possible, the limitations of a particular test and measurement to locate a fault are provided and recommendations are made regarding specialized fault-locating techniques.

What Is The Training Course Methodology?

This training methodology illustrates the concepts involved in the above areas through practical consideration of actual real-life problems, as well as explanation of concepts by experts in area using video projectors and computer aided case studies based on practical applications. Participants will solve their system problem, where the trainee’s try to apply the skills learnt with guidance from our specialized experts. ACAD will provide participants a comprehensive assessment on the problems solved using the skills acquired in the training course.
