The GA11 analytic instrument from WIKA combines precise sensing technology, intuitive operation and a robust design. It has been completely redesigned to carry out gas analyses in SF6 insulation systems reliably, reproducibly and in accordance with standards – with as little effort as possible for users.
Gas analyses are among the most critical tasks in the operation of high- and medium-voltage switchgear. This is because purity, humidity and decomposition products are decisive factors for insulation performance and operational safety. Maintenance companies, grid operators and testing service providers require measuring instruments for their analyses that are precise, stable and reliable under real operating conditions. The GA11 has been designed to provide optimum support for this daily practice.
Technological innovations for greater safety and compliance with standards
Regulatory requirements such as IEC 60376 or IEC 60480 demand measurements with high precision and reproducibility. The GA11 covers all relevant parameters:
- Digital sensor architecture for purity, humidity and decomposition products
- Humidity measurement under pressure for stable values under real operating conditions
- Wide calibration range from -10 °C to +50 °C
- Automatic measurement that detects sensor stability and terminates the process independently and intelligently
- Data export via QR code and USB for complete documentation
- Advanced service functions such as “Cleaning cycle”, “External evacuation” and “Purge hose”
Diagnostics for faults and error analysis
Unexpected increases in humidity and decomposition products can indicate arcing events, leakage or chemical ageing processes. The GA11 provides all relevant parameters in a clearly legible format, supplemented by structured reports with detailed data sets. This allows trends to be identified and decision-making processes to be documented in a comprehensible manner.
Operation via touchscreen with logical menu navigation
Quality control in manufacturing and workshop operations
The instrument is designed for use in a variety of locations, and a capacitive 10″ touchscreen, logically structured menus and an automated measurement process significantly reduce the complexity of operation. Weighing around 22 kg and powered by a NiMH battery, it is also exempt from dangerous goods classification during transport. Service providers and manufacturers benefit from fast measurement cycles and uncomplicated export formats that can be integrated directly into test procedures.
Guidance on technical and regulatory uncertainties
Gas analyses are technically challenging and error-prone processes. The GA11 supports this with reproducible measured values, automatic processes and clear display of limit values. Users therefore need to worry less about uncertainties regarding temperature compensation, calibration conditions or methods for humidity measurement. The combination of technical reliability and a transparent user interface makes it easier to achieve standard-compliant results and avoid error sources.
Focus on cost and risk awareness
Delayed decisions, unnecessary gas changes or unclear findings can quickly become costly for operators. The GA11 provides reliable measured values that allow conclusions to be drawn about necessary measures. Shorter process times – due to the elimination of repeat measurements – and a consistently structured workflow support economic decisions in operation, maintenance and also in production.
Conclusion
The new version of the GA11 offers modern, practical measurement technology combined with comprehensive documentation for operators and users. WIKA has developed an instrument that makes everyday processes easier for users by measuring precisely, providing clear guidance and functioning reliably under all conditions.
