Frequently Asked Questions
Do I need prior high voltage experience?

These courses are designed for existing electrical engineers and technicians who need training in specialist high-voltage areas, such as HV equipment testing, cable fault finding, and protection system maintenance.

Do I need to bring any high voltage test equipment?

No, all courses provide the specialist HV testing and cable fault-finding equipment required. Delegates focus on practical, hands-on training using industry-standard tools without needing to bring their own.

Why should I sit an HV testing course?

If you are an electrical engineer or technician working with high-voltage equipment, cables, or protection systems, taking a course will give you practical skills, confidence, and specialist knowledge to carry out safe testing, maintenance, and fault-finding. It’s particularly valuable for those working in utilities, industrial plants, or engineering services where HV expertise is critical.

Who is responsible for the maintenance of HV systems?

Responsibility for HV system maintenance typically falls to qualified electrical engineers and technicians within a company’s operations or maintenance teams. These professionals ensure high-voltage equipment, protection systems, and cables are regularly tested, maintained, and fault-checked to comply with safety regulations and industry standards. HV Testing & Maintenance Courses equip these engineers with the specialist skills needed to carry out these critical tasks safely and effectively.

Understanding HV Testing & Maintenance Courses

Our HV Testing & Maintenance Courses give engineers and technicians the confidence and expertise to work safely and effectively with high-voltage equipment. Through hands-on sessions, delegates develop a deep understanding of HV equipment testing, including procedures such as dielectric strength testing and protection system checks. Popular courses, like the City & Guilds HVTC1 Dielectric Strength Testing Course, provide structured guidance to build these essential skills.

We also specialise in HV cable jointing and fault finding, teaching practical techniques for testing, identifying, and repairing high-voltage cables. Delegates gain experience in spiking, sheath testing, and cable fault location, with courses such as the City & Guilds HVTC3 High Voltage Cable Spiking & Identification Course offering focused, real-world practice.

These courses are designed for professionals in power utilities, industrial maintenance, and engineering services, preparing them for roles where high-voltage expertise is critical. Delegates leave able to safely operate, maintain, and troubleshoot HV systems in substations, manufacturing plants, and other high-voltage environments.

By combining theory with extensive hands-on practice, our training develops technical confidence and practical competence. Engineers and technicians graduate ready to take on HV testing and maintenance roles, support operational reliability, and contribute to safe, efficient high-voltage systems across multiple industries.
