Testing and commissioning of electrical installations mark the critical final phase before energization of any power system—whether it’s an industrial plant, commercial building, or utility substation. This phase ensures that all installed electrical equipment and systems perform safely, efficiently, and in full compliance with design specifications, standards, and regulatory requirements.
In medium voltage (MV) power systems—typically operating between 1 kV and 36 kV—switchgear controls, protects, and isolates electrical equipment. Because of the high energy involved, minor operational errors can cause equipment damage or personnel injury. Interlocking systems are a critical layer of protection that prevent unsafe operating sequences and ensure reliable operation.
