GE DGA 900 TAPTRANS | 9 gas on-line OLTC DGA expandable with add-ons to a Transformer Monitoring System (TMS)
Complete DGA monitoring solution for transformers with On-Line Tap Changers (OLTC). All the features of TRANSFIX available for the transformer main tank and for the OLTC selector and diverter tanks.
Dissolved Gas Analysis (DGA) and moisture measurement of the insulation oil are recognised as the most important tests for condition assessment of transformers. Traditionally performed in a laboratory environment, TAPTRANS uniquely provides the capability as a single device to perform full on-line multi-gas DGA and moisture monitoring of a transformer main tank and on-load tap changer (OLTC), including both the selector and diverter tanks.
Applications
TAPTRANS uniquely provides asset managers with powerful insight into not only main transformer tank condition but also key OLTC parameters such as moisture level, current conductive system condition, mechanism timing characteristics, contact wear and insulation condition. The TAPTRANS is suitable for monitoring any oil filled transformer which has an OLTC, whether in-tank or on-tank, oil or vacuum tap, with a view to extending asset life, preventing unexpected failure and operating on a condition based / predictive maintenance schedule.
