Course Overview

*Please note, we are a 3rd party booker for this course which is delivered by National Grid Electricity Transmission*

The NG Competent Person – Overhead Lines: Application of Drain Earths (No Access onto Conductors) course provides delegates with the knowledge and practical skills required to safely apply drain earths to overhead line systems in accordance with National Grid Safety Rules.

This training focuses specifically on situations where drain earths must be installed without physically accessing the conductors, making it suitable for roles such as tower painters, maintenance teams, and those working in the vicinity of high-voltage overhead lines. The course aligns fully with National Safety Instruction 2 (NSI2) and reinforces the duties, responsibilities, and safety-critical requirements expected of National Grid Competent Persons.

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:
