Total Dissolved Gas Content ( TDGC ) for Insulation Liquids accord. To IEC 567 and IEEE C57.104-1991 Automatic analysis of the dissolved gases in oil-filled transformers The analysis is done in 2 steps which guarantee a very high selectivity and sensitivity of the determination of dissolved gases: 1. Gas separation by means of fully vacuum degassing ( accord. to DIN EN 60567, DIN IEC 599 and IEEE C57.104-1991) and display of results 2. Option: Subsequently to the determination of the total gas content a gas chromatographic analysis can be made. ENERGY SUPPORT Experts in providing mobile Solutions

ENERGY SUPPORT Sperberweg 47 D - 41468 Neuss/Germany Both steps are synchronized via a micro-processor control thus a fast and reliable measurement procedure is guaranteed Vacuum Degassing A new invented vacuum degassing method (Patent pend. DE 102 52 652 4) degasses the oil sample multi-periodical. After extraction through a 4 step vacuum pump the gases are dosed into vacuum chamber and separated. The gases are evacuated from the vacuum chamber with a vacuum pump; therefore a very high sensitivity can be reached. The measuring principle is shown in fig, 1. In and outlet of the oil sample...

The injection of the gas sample into the gas chromatograph is via a fixed mounted and heated transfer pipe. An additional port for withdrawal of gas samples is installed. Control and Evaluation The system is controlled by a micro-processor; a serial interface (RS 232) allows transferring the data to a remote computer. The intervals of the analysis cycle can be freely defined by the operator (number of analysis/day or hour). The system has 8 additional analog inputs (0 -1 V) for the measurement of other transformer parameters (Oil temperature, winding temperature, ambient conditions etc.)...
