2. Design and function

2.2 Description

Data processing and data storage

The analytic instrument model GA11 is a multi-sensor system for examining the quality

of SF₆ gas and g³ gas, e.g. in switchgear. The basic instrument consists of a built-in

computer with touchscreen for processing and storage of up to 500 data records. The data records can be exported via the integrated USB interface.

The accompanying software “Q-Analyser Measurement Viewer” enables you to display

the data on a PC or print the measurement reports (only for SF₆-Q-Analyser).

Extendable sensor system (only for SF₆-Q-Analyser)

The sensor system of GA11 is module-based and can be extended to up to 7 sensors. In addition, there is the possibility of storing measuring gas internally as well as pumping it back into the original gas compartment without losses after the measurement.

Automatic adjustment of the gas quality

After the measurement, the results will be compared with customer-specically adjustable limit values according to e.g. CIGRE B3.02.01 or IEC 60480 standards. The operator thus obtains a reliable statement on whether the insulating gas is suitable for the given application or not, or whether it is necessary to perform a gas processing or a gas exchange.

There are no

standards

to compare with for g³ gas.

The operator can enter his own limit

values for quality.

Battery life

If the lithium-ion accumulator is fully charged, the analytic instrument can perform at least 5 measurements with the “back pumping” function. The number of the battery-powered pump-back cycles is largely dependent on the tank pressure of the gas to be measured. The GA11 sends a warning message on the display when battery is low.

If the instrument is not connected to the mains in time, it will shut down automatically in order to prevent damages and data loss. In the mains operation, the battery is charged and the instrument can be switched on again at the same time and operate without restrictions.

Power and charging indicators

The front control panel has two LEDs which indicate the charging status (red) or mains operation (green).

If an error occurs during the charge cycle, the charging indicator ashes (red).
