TOGA GC 2 Dissolved Gas Analysis with Automated Full Vacuum Degassing

Gas-in-oil-analysis
Dissolved gas analysis with automated full vacuum degassing
Product description
The TOGA GC 2 has been designed for a fast and reliable measurement routine. The analysis – done in 2 steps – follows the ASTM and IEC standard guidelines. For many
decades Dissolved Gas Analysis has proven to be a favourable method for insulation diagnostics. The TOGA GC 2 has been developed to be user-friendly and delivers reliable and accurate results. The analysis system allows a calibration of the complete system following the measurement routine.

Degassing - Total Gas Content

Total Gas Content
Equally important for insulation diagnostics is the Total Gas Content (TGC).
The TOGA GC 2 is currently the only system which measures the TGC during the degassing process accurately. The increase in the TGC is a clear indication of existing faults in the transformer, which can be thermal, electrical or mechanical in nature.
The analysis is done in 2 steps with high selectivity and accuracy, fully compliable with laboratory procedure. Degassing of the oil sample is done through multi-periodic vacuum extraction (according to ASTM D 3612 and IEC 60567). The gas sample is automatically transferred to the GC. Gas chromatographic analysis is done with a Thermal Conductivity Detector (TCD), Flame Ionisation Detector (FID) and with a Methanizer. All results are displayed in ppm, sensitivity is as low as 0.1 ppm for hydrocarbons. Therefore, new transformer oils and transformers following their periodic maintenance can also be analysed. Besides the results, all other operating conditions are registered and stored in a file together with all remaining parameters. The graphics of the results is displayed in real time on the monitor, in the table or/and as a test report in a print file. The integrated Expert System will evaluate the results according to international standards like „Duval“ or „IEC“.

Automated version
The auto sampler technology has been designed to increase the efficiency of the TOGA system to make it more user-friendly and cost-efficient. The auto sampler is available for syringes with 30 or 50 mL and with 16 or 32 positions. It provides optimum value, time-efficiencies and excellent performance. There is no longer a need to change sample containers once the oil sample is taken from the transformer. Simply plug your syringe into the sample tray – absolutely contamination free.
