Introduction:

High-voltage electrical systems such as 11 kV and 132 kV networks are critical components of modern power distribution and transmission infrastructure. Working on or near these systems requires not only technical competence but also strict adherence to safety regulations, procedural control, and regulatory compliance. This training program, designed by Global Horizon Training Center, is tailored for experienced electrical professionals who are being prepared or refreshed to act as Senior Authorized Persons (SAP) for high-voltage operations.

The program focuses on the practical and theoretical aspects of operating, isolating, testing, and issuing safety documents in HV systems. It provides a comprehensive understanding of electrical safety rules, switching procedures, risk assessment, and emergency response. It ensures that candidates demonstrate the competence and confidence required to manage work safely and effectively on live and de-energized HV systems up to 132 kV.

Objectives:

By the end of this training, participants will be able to:

• Understand the responsibilities of a Senior Authorized Person (SAP)

• Identify and interpret safety documentation for HV systems

• Apply correct procedures for switching, isolation, and earthing

• Assess risks and implement appropriate controls

• Issue and cancel permits and safety documents

• Respond appropriately to HV incidents or emergencies
