This course provides an in-depth familiarisation with the components of a typical renewable asset High Voltage(HV) electrical installation including the protection and control sub-systems.

This course will also describes the function / normal operation of the asset and typical faults.

We will also outline the documents and records associated with HV electrical plant and describes best practice in the monitoring of a HV system.

This is module 1 of our electrical courses. Information on Module 2 - Due Diligence for Procurement and take over of HV Installations and Module 3 - Management & Control of Electrical Installations and Application of IS EN 50110 1&2 can be found by clicking the links

This course will provide an overview of Legislation, Standards and Industry Guidance relevant to the Operation of HV electrical installation.

• High Voltage (HV) Electricity Systems of Windfarms.
• Terms and abbreviations used in the management of HV systems.
• Single Line Diagrams and how they relate to the system.
• Components of a HV system.
• Hazards and Risks associated with operating a HV system.
