What is BS EN 60567 - Oil-filled electrical equipment gases sampling about?
BS EN 60567 deals with the techniques for sampling free gases from gas collecting relays from power transformers. Three methods of sampling free gases are described in BS EN 60567 . The techniques for sampling oil from oil-filled equipment such as power and instrument transformers, reactors, bushings, oil-filled cables and oil-filled tank-type capacitors are no longer covered by BS EN 60567 . Before analysing the gases dissolved in oil, they are first extracted from the oil. BS EN 60567 describes three basic methods, one using extraction by vacuum (Toepler and partial degassing), another by displacement of the dissolved gases by bubbling the carrier gas through the oil sample (stripping) and the last one by partition of gases between the oil sample and a small volume of the carrier gas (headspace).
