| 1 | Due to disturbances/ transients from the power system as well as increasing age of the transformer population, onsite diagnostic testing and condition assessment are important to secure a reliable operation of the electrical power system. For this purpose, offline and online diagnostic methods for power transformers have been developed which offers the possibility of detecting incipient faults. Offline diagnostic methods are used mainly during scheduled inspections or when transformer trips and it is suspected that the transformer has failed whereas online methods are used during the operation and offer a possibility to record the parameters and monitor the condition under realistic operating conditions (e.g., electric field, load, and temperature). | |
