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.
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“.
Applications
- Insulating oil
- Gear oil
- Mineral oil

Advantages
- One-touch operation
- Accurate measurement of total gas content
- Most sensitive detection for Acceptance-, Service- and Routine tests (0.1 ppm)
- Adaptable for Factory Transformer Heat-Run tests
- Ideal solution for laboratories and workshops
Features and Results
- Fully automatic procedure
- Multi-periodic vacuum degassing
- Full Dissolved Gas Analyses (11 gases) and Total Gas Content
- Automatic transfer of gas sample
- Easy calibration of the whole system with traceable calibration gas
- Auto sampler available for 16 or 32 samples for unattended operation
- Expert System for quick and easy result evaluation
- Evaluation according to: IEC 60599, Roger ratios, Duval etc.
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.
