Dissolved Gas AnalysisSee our other links at:
DGA EXPERT SYSTEMS SOFTWARE
The most important aspect of fault gas analysis is taking the data that has been generated and correctly diagnosing the fault that is generating the gases that have been detected.
We have put together here diagnostic methods for determining
type faults. Other methods will be available on future upgrades of
Interpretative or Key Gas Method
Useful if no measured previous dissolved gas history is available. The data is compared to the majority of transformers. Flag limits indicated here are established by NTT and utilitized on NTT reports. Customers can establish different flag limits on our reporting software.
Dornenburg Ratios.................(under construction)
IEEE\ANSI C57.104 Guidelines...(under construction)
We are in the process of updating our on-line diagnostic software. Improvements will include gassing limits, IEEE Guildelines, and various gas ratio methods.
We are, however, very interested in knowing how valuable this service is to our web site customers. It is through your comments and suggestions that this website evolves.
