The application of neural networks to the analysis of dissolved gases in insulating oil used in transformers
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
The application of neural networks to the analysis of dissolved gases in insulating oil used in transformers
(Institute of Electrical and Electronics Engineers (IEEE), 2000-01-01)
The state of insulating oils used in transformers is determined through the accomplishment of physical-chemical tests, which determine the state of the oil, as well as the chromatography test, which determines possible ...

Power Transformer Condition Assessment Using DGA and FRA
(Institute of Electrical and Electronics Engineers, 2016-11)
Power transformer condition assessment is a very complex task but also of high priority for power system reliability. Several diagnosis techniques have been published, specifically; insulation system condition assessment ...
Fast fault diagnosis in power transformers using optimum-path forest
(2012-10-01)
In this paper we propose a fast and an accurate method for fault diagnosis in power transformers by means of Optimum-Path Forest (OPF) classifier. Since we applied Dissolved Gas Analysis (DGA), the samples have been labeled ...

Effect of dissolved oxygen concentration on red pigment and citrinin production by Monascus purpureus ATCC 36928
(Brazilian Society of Chemical Engineering, 2008)
The present study investigated the effects of agitation speed, N (200, 500, 600 or 700 rpm), and dissolved oxygen concentration, C (120, >70, 70, 60, 10 or < 10%), on red pigment and citrinin production by Monascus purpureus ...
Reassessment of the estimation of dissolved oxygen concentration profile and K(L)a in solid-state fermentation
(ELSEVIER SCI LTD, 2000)
Oxygen mass transfer in aerobic microbial growth systems is often a limiting factor for optimal growth and productivity. Oxygen mass transfer has been widely studied in submerged fermentations but has attracted as yet ...
