“…Several monitoring detectors can provide on-line measurements of four key gases 11 (H 2 , C 2 H 2 , C 2 H 4 , and CO), the total combustible gas 12 , or the hydrogen gas concentration 13,14 are commercially available. Although these monitors are useful warning devices, they do not, however, provide a complete fault assessment.…”

This paper describes the feasibility of using a quadrupole mass spectrometer-based gas analyzer to predict malfunctions in high-voltage oil-filled power transformers using the analysis of dissolved gases in oil technique. A vacuum system for the quadrupole analyzer and the gas introduction system is designed and built for this purpose. A method for the extraction of the dissolved gases in oil is developed and the gas introduction system is described. The spectra of the thirteen gas species of interest are obtained and the sensitivity factors for each gas are calculated. The spectra of a standard gas mixture and the dissolved gases in oil from a faulty transformer oil specimen are obtained. The data reduction procedure is described and is used to reduce these spectra to the partial pressures of the 13 gas species. Finally, the concentration of each gas is calculated and methods for fault assessments are presented.

Detailed procedures for analyzing gas from gas spaces or gas-collecting devices as well as gas dissolved in oil are described. The procedures cover: (1) the calibration and use of field instruments for detecting and estimating the amount of combustible gases present in gas blankets above oil, or in gas detector relays; (2) the use of fixed instruments for detecting and determining the quantity of combustible gases present in gas-blanketed equipment; (3) obtaining samples of gas and oil from the transformer for laboratory analysis; (4) laboratory methods for analyzing the gas blanket and the gases extracted from the oil; and (5) interpreting the results in terms of transformer serviceability. The intent is to provide the operator with positive and useful information concerning the serviceability of the equipment. An extensive bibliography on gas evolution, detection, and interpretation is included.
