Course Description


This training course is split into two modules:

MODULE I - TAMCO High Voltage Switchgears

MODULE II - Transformer Operational Principles , Selection & Troubleshooting

Each module is structured and can be taken as a stand-alone training course; however, delegates will maximise their benefits by taking Module 1 and 2 back-to-back as a 2-week training course.
