Course Overview
Participants acquire the knowledge and skills to perform and operate diagnostic tests (conventional or advanced as FRSL measures, FRA, FDS) on power and distribution transformers. Subsequently this knowledge is embodied in practical work.
Course Objective
- Perform diagnostic measurements on transformers
- Interpret and evaluate the measurement results
- Correlate results from different measurement methods
Who Should Attend??
Technicians and engineers from utilities or companies responsible for maintenance and diagnostics of power transformers.
