Fault Finding on Electrical Power Systems (Ref:OTSFFEP001)

Course Objectives

To gain a detailed understanding of fault finding on Electrical Power Systems.

Course Description

This course is designed to increase the fault diagnostic skills of engineers and maintenance teams on Power Station and distribution systems. The practical elements of the course centre on advancing the candidate’s knowledge of risks, faults and hazards on modern HV switchgear; motors and power station HV systems. The course will progressively move toward advancing the candidate’s knowledge of the faults and their rectification on complex electrical systems.

Who Should Attend

Electrical Engineers who have the responsibility for maintaining local electrical power distribution and operating networks. Engineers who need to trouble shoot on many different systems and need to advance their knowledge of fault finding techniques to reduce down time.

Pre-Requisites

All Attendees should have a sound power generation and electrical background.

Course Outcome

At the end of this course you will be able to find faults on electrical power systems.
