摘要： This application relates to method and apparatus for gas analysis. An apparatus (200) may have a first reflector (103) and a second reflector (104) positioned on either side of a sample volume (202) for a gas sample. The configuration of the first reflector may be variable between at least first (103a) and second (103) configurations, wherein each of the first and second configurations is arranged such that a beam of optical radiation from an optical beam origin (210) is directed to a detector location (212) via the sample volume. In the second configuration the beam of optical radiation is reflected at least once from each of the first and second reflectors and the path length of the beam of optical radiation through the sample volume is greater than in the first configuration.

摘要： Certain embodiments of the disclosure relate to a bi-directional oil-flow adapter (115) that is attachable to a valve-controlled port (110) of a transformer housing (100) in which oil is contained for cooling parts of the transformer (105) such as a primary coil and a secondary coil. The bi-directional oil-flow adapter (115) not only allows for an oil sample to be drawn out of the transformer housing (106) via the valve-controlled port (110) but also allows for the oil sample to be used (along with an additional volume of oil if so desired) for flushing the valve-controlled port (110) in order to ensure that a subsequent oil sample is different than a current oil sample. The oil sample can be provided to a dissolved gas analyzer (135) for detecting and analyzing one or more gases that may be present in the oil sample, the one more gases indicative of a level of contamination of the oil sample.
