Secondary Systems Services

Secondary systems are a critical component of any HV system – providing protection and control to your primary plant assets, and enhancing the reliability, safety and performance of plant. Secondary systems are often complex and connect to multiple remote systems, requiring thorough planning and an experienced team to ensure system security is maintained at all project stages.

PBA understands this well. We recognise that secondary systems are all about protecting personnel and equipment, whilst maintaining maximum asset availability and security.

Our market-leading expertise spans all industry segments – generation, transmission and distribution – and a wide range of protection and control schemes/equipment. We offer specialist end-to-end testing and commissioning services for complete substations, including all protection, SCADA and control equipment.
