Due to factors such as grid digitalisation and the advanced age of the installed transformer fleet, online DGA for transformers is entering a period where its usage has become widespread. This article from Megger’s V. Oppedisano and M. Pinard covers the historical development of the DGA sensors and sensing techniques as well as today’s mature technology sensors, with a particular emphasis on tuneable diode laser spectroscope.
This article discusses a new technology where a dedicated laser is used for the critical measurement of acetylene dissolved in oil at a cost-effective price that facilitates the justification of deployment in a wide range of applications for low- and medium-power, as well as for high-power transformers.
