SDB – Smart Device Expert Bushing, CT and PT Monitor
Condenser bushings are subject to stress due to transient over voltages like surges and atmospheric discharges. Combined with the fact that they are impossible to test when the equipment is energised, they are one of the main areas of failure in transformers and reactors. Heavy fines are imposed when the equipment is unavailable during off-line…
SDG – Smart Device Expert Gas and Moisture Monitor
Detecting the presence and evolution of gases dissolved in the insulating oil of high voltage equipment like power transformers and reactors is a proven and efficient tool for diagnosing their internal condition. Measuring these gases in the laboratory through gas-chromatography tests in samples of oil taken periodically(months/years) from the equipment can eventuate in the possibility…
