Description
High voltage instrument transformers are critical components within electrical transmission systems. They are present in all substations, switchyards, and electrical grids. Despite this, their purpose is often misunderstood. When you have finished this course, you will know:
- Where high voltage instrument transformers are used within the electrical system/grid.
- How they work (operational theory).
- Their applications (metering, protection etc.).
- Their main components.
- The different designs that are available.
- What factors influence their application (burden, accuracy, insulation level etc.).
This course is essential if you are working in the power generation, power transmission, or power distribution industries.
