Program Professional Framework
Certified 11KV Electrical Safety
Program Overview
Work on 11kV distribution networks, ring main units and industrial substations carries shock, arc flash and switching error risks that require strict systems of work. This programme covers the hazards of medium voltage equipment, safety rules and authorisation levels, switching programmes, isolation and earthing, proving dead with approved voltage detectors, permits to work and sanctions for test, and arc flash protection. Participants practise planning and checking switching operations on typical 11kV arrangements used by utilities and industrial plants in the Gulf.
Learning Outcomes
- ✓Identify the shock, arc flash and induced voltage hazards specific to 11kV switchgear, cables and transformers.
- ✓Prepare a switching programme for isolating a ring main unit or feeder with correct sequence and checks.
- ✓Apply isolation, proving dead and earthing steps before issuing a permit to work.
- ✓Select arc-rated PPE and tools appropriate to the task and incident energy level.
- ✓Explain the duties of authorised, competent and instructed persons under company electrical safety rules.
- ✓Respond correctly to an 11kV electrical incident, including safe rescue and reporting.
Target Audience
- Electrical engineers and technicians working on 11kV systems
- Authorised and senior authorised persons for HV switching
- Substation and distribution network operators

Training Methodology
Applied Project & Assessment
Applied Project
Participants prepare a complete safe work package for maintenance on an 11kV feeder circuit breaker: single-line extract, switching programme, isolation and earthing points, permit to work content, PPE selection and the restoration sequence.
Assessment
Short diagnostic at the start, practical tasks linked to each learning outcome, and evaluation of the applied project against published criteria.
