Substation Maintenance

Substation maintenance involves periodic planned inspections, checking, testing and troubleshooting, to ensure the correct operation of all components and their interaction. Typical inspection and diagnosis processes include, among others, transformers, breakers, protection relays, overhead lines and switchgear in general. In order to perform these actions, extensive knowledge is required on the operation and maintenance of these components.

The courses in this area of expertise provide a comprehensive insight into operation of switchgear, transformers, overhead lines and relay protection, required testing regime and effective maintenance program for each of the substation components. It provides very practical guidance for safety, maintenance scheduling, operational and testing procedures, troubleshooting and interpreting test results, required to achieve long service life and uninterrupted operation of substations.

The following courses fall in this group:
