Primary Electrical Engineer (HV Earthing Systems)
Overall Job purpose:
As an Earthing Design Engineer, you will be responsible for the design and analysis of grounding systems specifically for switch houses and substations up to 400kV, ensuring the safe dissipation of fault and lighting currents to protect both people and station assets. The Earthing Design Engineer will primarily use CDEGs to model earth grid performance, assess step and touch voltages, and ensure compliance with standards such as BS EN 5022, IEEE 80 and National Grid TS 3.1.1/3.1.2, all based on site-specific soil resistivity and system fault levels.
Main Duties & Responsibilities:
1. Lead the design of substation and site-wide earthing systems for AIS and GIS Substations up to 400kV
2. Use software such as CDEGS and XGSLab to perform detailed earthing studies
3. Support teams and conduct site resistivity testing and field measurements
4. Interpret technical data, soil investigations and client specifications to develop optimal earthing designs
5. Produce detailed design documentation, including drawings, calculations and reports
