NG Competent Person Overhead Lines CPC LAC & PFW Application of Drain Earths

This NG Competent Person OHL Drain Earths Training course provides detailed training on the safe, compliant application of drain earths to overhead line systems where no access onto conductors is required. Delegates will work through both theoretical learning and practical demonstrations covering:

National Grid Safety Framework

• Overview of National Grid Safety Rules
• Scope and requirements of NSI2 – Work on or near HV Overhead Lines
• Understanding Safety Documents, including Permits, Limitations of Access, and Sanction for Test
• Roles and responsibilities of a Competent Person (CP) within the National Grid environment

Principles of Drain Earthing

• Purpose and function of drain earths in OHL environments
• Situations requiring the application of drain earths without conductor access
• Equipment identification, selection and inspection
• Understanding electrical induction, fault currents and equipotential zones

Safe Work Procedures

• Step-by-step procedure for applying drain earths from ground level
• Establishing safe working distances and exclusion zones
• Working under issued Safety Documents
• Visual checks, communication protocols and in-field verification
• Common hazards and how to mitigate them

PPE & Safety Controls

• Required PPE for overhead line earthing activities
• Additional task-specific safety equipment
• Pre-task briefings, dynamic risk assessments and toolbox talks

Documentation & Compliance

• Using technical drawings, site diagrams and OHL identification markings
• Recording activity and updating logs in accordance with National Grid standards
• Understanding escalation procedures and emergency actions

Practical Application

• Demonstration of correct drain earth installation techniques
• Supervised practical exercise applying drain earths to training structures
• Instructor review and feedback on technique, safety and compliance

By the end of the course, delegates will be able to:

• Correctly apply drain earths in accordance with NSI2 without accessing conductors
• Understand their responsibilities as a National Grid Competent Person (CP)
• Identify hazards associated with overhead line work and implement appropriate control measures
• Select, inspect and use earthing equipment safely and effectively
• Interpret Safety Documents and operate within formal National Grid procedures
• Demonstrate safe working practices during the practical assessment
• Communicate effectively with Authorised Persons, team members and safety controllers
• Maintain compliance with National Grid Safety Rules and local procedures
