HV | LV Testing
Get Our Dedicated Teams For Your Most Complex Systems
SESC offer a complete solution for your HV, LV systems that begins with the testing and commissioning plan and ends with the successful start up load testing of all system.
Whether it's Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), Phased commissioning or loads testing our expert engineers have the skills and experience to commission even your most complex systems. We use our extensive library of Inspection and Test Plans, Procedures, Test Verification documents, and Method Statements to document all activities and provide you independent verification of our systems readiness for handover.
We provide our clients with a comprehensive testing and commissioning service on a wide range of HV, LV system assets including power transformers, current & voltage transformers, circuit breakers, switchgear, protection relays, revenue meters, earthing systems, cables etc.
Development of commissioning plans, procedures and verification documents for projects and to provide recommendations if necessary.
