Condition Based Monitoring of Transformers
Monitoring approach suited to the needs of the customer remote connection
Paying higher attention to vital equipment >> Transformers are valuable components in electrical power networks. >> Outages have not only financial repercussions, they also impact on the stability of the grid. Condition monitoring of transformers >> Online information on the actual operation conditions and calculation of the condition and ageing behaviour help to avoid unexpected outages. >> Furthermore it allows for a more efficient and profitable transformer exploitation. Condition based monitoring of transformers >> Basic condition monitoring as solid base. >> Advanced condition monitoring on an as-needed basis. Condition based maintenance of transformers >> Condition based monitoring backed up by an adjusted maintenance scheme will extend the life-time of the transformer and increase its availability.
Basic condition monitoring Early warning system i.e. detection of typical fault gases >> Partial discharges -> H2 >> Excessive heating of paper -> CO Monitoring of important transformer data >> Top-oil & ambient temperature >> Transformer loading >> Tap position >> Cooling stage >> Moisture-in-oil Loss-of-life calculation >> Hot-spot temperature >> Relative ageing rate & accumulated loss-of-life
