Gnosys has used its experience in on-line analysis and electrical systems to develop a variety of hand-held spectroscopic probes, including a 4-m long flexible probe with integrated imaging and wide-wavelength spectroscopy, to perform in-tank inspection of high voltage power transformers and other similar hardware. The nature of the probe is such that inspections can be made without the transformer being drained or "de-tanked".
The combination of imaging and spectroscopy enables the operator to quickly ascertain the quality of the electrical insulation system, which combined with the visual inspection, enables timely and cost-effective interventions to maximise plant life and limit unexpected outages.
This system has been developed and trialled successfully with SSE and further developments are being pursued.
