1 Introduction
2 Scope
3 Recommended basic method for interpreting gas
analysis
3.1 Gases generated from oil
3.2 Levels at which dissolved gases are significant
3.3 Diagnosis of faults from relative concentrations of
individual gases dissolved in oil
4 Degradation of cellulosic insulation
4.1 Examining CO2 and CO concentrations found dissolved
in oil
4.2 Examining CO2 and CO concentrations in free gases
found in the gas-collecting relay
5 Application of diagnostic method to free gases in
a gas-collecting relay
5.1 Calculation of dissolved gas concentrations
equivalent to free gas concentrations
Appendix
A Information obtained from rates of gas production
Describes the means by which the concentrations of dissolved gases or free gases previously removed from the oil by the techniques described in BS 5574, may be interpreted to diagnose the condition of a transformer in service and suggest future action.
