Services
Rail Electrification
Specialist rail electrification services covering AC/DC traction systems, overhead line testing, and substation commissioning. Our engineers deliver Network Rail-compliant solutions for new installations and upgrades, including autotransformer schemes and SCADA integration. With proven experience on major programmes like the Great Western Mainline, we ensure systems meet safety and operational standards while minimising service disruption.
High Voltage Testing
Comprehensive high voltage testing and commissioning for switchgear, protection equipment, and power systems. Our ISO-certified processes include synchronised injection testing, protection relay validation, and cable fault diagnostics. Engineers perform AC pressure testing and functional assessments to ensure compliance with industry standards and operational reliability across rail and offshore sectors.
Substation Maintenance
Full lifecycle substation maintenance and modernisation services, including switchgear upgrades, control system integration, and safety protocol implementation. We specialise in GIS substation conversions, vacuum circuit breaker replacements, and IEC 61850 configuration. Our team ensures continued operation of critical infrastructure through planned maintenance and emergency fault resolution.
Offshore Power Systems
Offshore power supply system testing and commissioning for oil platforms and renewable energy installations. Services include HV interconnector installation, switchgear validation, and safety-critical system integration. We follow strict offshore safety protocols and have completed projects like the Montrose Alpha BLP HV interconnector, ensuring reliable power distribution in challenging environments.
Protection Relay Testing
Advanced protection relay testing for intelligent electronic devices in rail and power networks. Our engineers validate protection schemes, perform dynamic testing using GPS-linked equipment, and ensure compliance with protection coordination studies. This service maintains system integrity and prevents operational failures in critical infrastructure.
