Senior HV Transients & Insulation Coordination Engineer
Are you an expert in electromagnetic transients, insulation coordination, and surge protection looking to take ownership of a highly specialised technical discipline? We're seeking a Senior HV Transients & Insulation Coordination Engineer to lead complex power system studies across a diverse portfolio of energy and infrastructure projects.
The Role
As the technical authority for transient analysis and insulation coordination, you'll support projects from concept development through FEED and detailed design, ensuring critical electrical assets are protected against overvoltages and transient events.
Key responsibilities include:
- Leading electromagnetic transient studies for high-voltage power systems
- Performing switching surge analysis, transformer energisation studies, cable energisation assessments, and lightning surge modelling
- Evaluating transient risks across substations, industrial facilities, renewable energy projects, battery storage systems, microgrids, and power distribution networks
- Developing insulation coordination philosophies and equipment withstand requirements
- Specifying surge arresters, insulation levels, electrical clearances, and overvoltage protection measures
- Supporting tendering and business development activities by identifying technical risks and validating engineering solutions
- Collaborating with multidisciplinary engineering teams to ensure equipment specifications align with calculated transient stresses
- Delivering technically robust recommendations in accordance with BS, IEC, and IEEE standards and industry best practice
- Presenting complex analytical findings to clients in a clear and practical manner
About You
You will have:
- Degree qualification in Electrical Engineering, High Voltage Engineering, Power Systems Engineering, or a related discipline
- Minimum 5 years' experience in HV transient analysis, insulation coordination, surge protection, or power system studies
- Strong proficiency with PSCAD, EMTP-RV, ATP-EMTP, or equivalent electromagnetic transient simulation software
- Detailed understanding of:
- Switching transients
- Lightning phenomena
- Transformer inrush currents
- Resonance and ferroresonance
- Cable energisation effects
- Surge propagation and overvoltage protection
- Experience working with transformers, reactors, GIS/AIS switchgear, underground cable systems, and industrial power networks
- Strong knowledge of insulation coordination principles, surge arrester selection, dielectric withstand requirements, and protection strategies
- Familiarity with applicable BS, IEC, and IEEE standards
- Excellent communication and stakeholder management skills
- Authorisation to work in the United Kingdom
Desirable Experience
- Renewable energy projects
- Battery Energy Storage Systems (BESS)
- Industrial electrification
- Critical infrastructure developments
- Microgrid design and operation
Why Apply?
This is an opportunity to become a recognised specialist within a growing engineering team, supporting technically challenging projects across renewable energy, industrial power systems, energy storage, and critical infrastructure sectors.
The role offers the chance to remain hands-on technically while influencing key engineering decisions that help clients minimise risk, optimise asset performance, and protect major capital investments.
Requirements
- 5+ years' experience in Engineering
- 5+ years' experience in Electrical Power Systems
- 5+ years' experience within Renewable or Alternative Energy projects
- Eligible to work in the United Kingdom
