SJB Smart Electricals HV Authorised Person / Responsible Person training is intended for suitably experienced electrical and engineering personnel who may be considered for responsibility within an organisation’s High Voltage electrical safety structure.
The programme focuses on the responsibilities associated with controlling HV systems, understanding switchgear, planning switching and isolation, applying electrical safety rules, managing permits and establishing safe working conditions.
- Experienced electrical engineers
- HV maintenance engineers
- Electrical supervisors
- Estates and infrastructure engineers
- Personnel being developed towards HV AP duties
- Existing APs requiring refresher or development training
What Is High Voltage?
Within common UK electrical safety definitions, Low Voltage extends up to 1,000 V AC or 1,500 V DC between conductors. Electrical systems above the defined LV range are normally treated as High Voltage.
HV installations may include substations, transformers, ring-main units, circuit breakers, HV cables, protection systems and associated Low Voltage distribution.
The increased system energy, switching requirements and consequences of incorrect operation mean that HV systems require highly controlled procedures and appropriately trained, experienced and authorised personnel.
High Voltage
or above the applicable Low Voltage range.
Typical HV environments include substations, distribution networks, industrial facilities, airports, healthcare estates, manufacturing sites and critical infrastructure.
Why HV Authorised Person Training Is Different
Working with or controlling HV electrical systems goes considerably beyond normal LV electrical maintenance. Safe operation depends on system knowledge, switching discipline, precise communication and rigorous control of safety documentation.
HV Distribution Systems
Understand the structure and operation of high-voltage distribution networks and their relationship with LV systems.
HV Switchgear
Develop understanding of circuit breakers, disconnectors, ring-main units and common HV switching equipment.
HV Switching
Understand planned switching sequences, system status, communication and operational control.
HV Isolation
Understand how safe working conditions are established, secured and controlled before HV work takes place.
Safety Documentation
Apply permit-to-work systems, switching schedules, sanction-type documents and other applicable safety controls.
Protection & Faults
Develop awareness of protection systems, fault conditions, system energy and the consequences of incorrect operation.
What Can the HV AP Training Programme Cover?
The final programme should reflect the electrical systems, safety rules, operational duties and previous experience of the delegates. Typical topics include:
HV Electrical Safety
Electrical hazards, system energy, electric shock, arc-related risk, Electricity at Work Regulations and safe working principles.
HV Distribution
High-voltage network arrangements, transformers, substations, feeders and the interface between HV and LV systems.
HV Switchgear
Common switchgear types, circuit breakers, ring-main units, disconnectors, earth switches and equipment identification.
Roles & Duties
Responsibilities of Authorised Persons, Senior Authorised Persons where applicable, Competent Persons and other safety roles.
Electrical Safety Rules
Application of company safety rules, operational procedures, system control and defined authority.
HV Switching Procedures
Planning and recording switching operations, communication, system status and controlled sequence of operation.
Isolation & Earthing
Principles of safe isolation, proving system state, application of earths and establishing a safe place of work.
Permits & Safety Documents
Preparation, issue, control, suspension and cancellation of relevant electrical safety documentation.
Protection Systems
Introduction to electrical protection, fault clearing, interlocks and the role of protective systems within HV networks.
Operational Scenarios
Practical and classroom exercises based around switching, isolation, safety documents and HV operational decisions.
HV Training Is Intended for Suitably Experienced Personnel
High Voltage Authorised Person training is not an entry-level electrical course.
Delegates being considered for HV responsibilities should normally have an appropriate electrical or engineering background and sufficient knowledge and experience for the duties they may eventually be authorised to undertake.
Where a delegate does not yet have the required experience, additional electrical training, supervised practical exposure or a staged competence-development programme may be more appropriate.
Before Booking, Consider
- Electrical qualifications and background
- Previous HV experience
- Type and voltage of the system
- Switchgear and network configuration
- Expected switching duties
- Company electrical safety rules
- Whether AP or SAP responsibilities are required
Course Completion ≠ Automatic Authorisation
A training certificate does not automatically authorise a person to operate or control every High Voltage electrical system.
Formal appointment should consider technical knowledge, experience, practical ability, familiarity with the actual installation, understanding of local safety rules and the defined limits of the person’s authority.
Building Genuine HV Competence
Effective HV competence is built through a combination of formal training, practical experience, site familiarisation, supervision and organisational appointment.
- Formal technical training
- Supervised HV operational experience
- Familiarisation with site switchgear
- Understanding of protection and network arrangements
- Site-specific safety-rule training
- Assessment of practical competence
- Formal written authorisation
