Bushings occasionally fall short as a consequence of partial discharge. This is sometimes a result of the slow and progressive degradation on the insulation around a few years of energized service; nonetheless, it may be considered a quick degeneration which destroys a good bushing within a subject of several hours. At this time, there is excellent curiosity with the energy supply market in monitoring the affliction of substantial-voltage bushings.
If not possible, assist of OEMs to interpret outcomes is recommended as they have got the model and instruments necessary to suitable for temperature results.
• temperature throughout subsequent measurements need to be similar to that of the ‘fingerprint’ measurement. The thermal time consistent of a large bushing can be extremely big, exceeding forty eight hours, and enough time has therefore being allowed with the temperature Within the full condenser core to stabilize.
