Testing and commissioning ensures that all the components of an electrical infrastructure are correctly functioning and installed before being put into full service. This includes the assessment of all protective components to ensure they are active and working when called into action, in the event of a fault. This helps to identify any issues before they become a problem later down the line, similarly to substation maintenance and transformer maintenance, and ensures that equipment meets safety and operational standards.
