Course Code
EPET-006
Selecting, Operating and Maintenance High-Voltage Cables
- This training course will present a comprehensive capsule of all the knowledge essential for the medium voltage and high voltage switchgear operations and walk the participants through the switchgear design process using a set of interlinked case studies. The training course focuses mainly on the operation and maintenance of distribution equipment namely transformers, circuit breakers, contactors, isolators and disconnectors.
- Medium and high voltages switchgears are the integral component of any electrical distribution system; hence, the selection and installation of these switchgears are vital to provide protection and safe distribution of electrical power.
