Kelman Transfix
Knowledge of the condition of transformers is essential for all electrical networks and on-line monitoring of critical transformers is increasingly vital. This information allows valuable assets to be maximised and expensive failures to be avoided. Dissolved Gas Analysis (DGA) and moisture measurement of the insulation oil are recognised as the most important tests for condition assessment of transformers.
Features & Benefits
The TRANSFIX unit is a new generation of on-line DGA equipment giving essential insight into the condition of transformers. Extensive field use proves that the TRANSFIX equipment provides reliable information and represents a valuable tool for Asset Management:
• Transformer faults detected in their infancy.
• Transformer output optimized safely, maximising asset
• Transformer ageing can be calculated.
• Type of fault can be classified from results.
Technical Features
• Uses photo-acoustic spectroscopy to give highly reliable results. Field proven in over ninety countries worldwide.
• Eight target gases plus moisture measured.
• Estimation of nitrogen and total gas content for free breathing transformers.
• Full embedded processor – over two years of data at a default sampling rate of one sample taken every four hours.
• Non-volatile memory storage to prevent loss of data.
• Discrete sampling gives more rapid response to gas rises. No ‘averaging’ of DGA results.
