Why High Voltage training matters
Working with high voltage carries serious risks. Without proper training, technicians face hazards that can impact both safety and asset performance.
GWO High Voltage training gives your teams the knowledge and skills to operate safely under a documented safe system of work. It ensures confidence in planning, switching, isolation, earthing, and cable pulling.
When technicians are trained in HV procedures:
-
Risks of electrical incidents are reduced
-
Tasks are performed consistently and safely
-
Authorisation pathways become clearer
-
Teams can respond effectively in emergencies
-
Projects run with fewer delays and stoppages
What we offer
Modules are GWO-certified and support progression toward employer HV authorisation.
Who it’s for
