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 N2 / CleanAir / DryAir, 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.

Extendable sensor system

The sensor system of GA11 is module-based and can be extended. 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. For gas mixtures based on N2 / CleanAir / DryAir, there might not yet

be any standards or limit values available. It is recommended that, before measuring

the gas quality, the requirements and the limit values are veried with the respective

manufacturer.

Battery life

If the lithium-ion rechargeable battery is fully charged, the analytic instrument can

perform at least 5 measurements with the “pumping back” function.The number of the

battery-powered pump-back cycles is largely dependent on the container 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).

Explanation of symbols

WARNING!

... indicates a potentially dangerous situation that can result in serious injury

or death, if not avoided.

CAUTION!

... indicates a potentially dangerous situation that can result in light injuries

or damage to property or the environment, if not avoided.

Information

... points out useful tips, recommendations and information for ecient and

trouble-free operation.

3.1 Intended use

3. Safety

Application areas

The instrument is especially designed for applications that full the following conditions:

■

The use is only allowed in buildings or dry surroundings.

■

Use only for commercial purposes and in industrial environment.

■

The height of the operation site should not exceed 2,500 m.

■

Environment with max. pollution degree of 3.

■

Voltage supply of overvoltage category II.

■

Ambient temperature between 0 ... 40 °C.

Only use the analytic instrument in applications that lie within its technical performance

limits (e.g. max. ambient temperature, pressure ranges, ...).

→ Performance limits see chapter 11 “Specications”.

The instrument has been designed and built solely for the intended use described here,

and may only be used accordingly.

Only use the instrument with original accessories from WIKA.

Refrain from unauthorised modications to the instrument.

Any use beyond or dierent to the intended use is considered as improper use.

The technical specications contained in these operating instructions must be

observed. Improper handling or operation of the instrument outside of its technical

specications requires the instrument to be taken out of service immediately and

inspected by an authorised WIKA service engineer.

Handle electronic precision measuring instruments with the required care (protect from

humidity, impacts, strong magnetic elds, static electricity and extreme temperatures,

do not insert any objects into the instrument or its openings). Plugs and sockets must be

protected from contamination.

The manufacturer shall not be liable for claims of any type based on operation contrary

to the intended use.

3. Safety

3.2 Personnel qualification

WARNING!

Risk of injury should qualication be insucient

Improper handling can result in considerable injury and damage to property.

■

The activities described in these operating instructions may only be

carried out by skilled personnel who have the qualications described

below.

■

Keep unqualied personnel away from hazardous areas.

Trained personnel

The plant operator must ensure that the handling of N2/ CleanAir / DryAir (gas

mixtures) is only carried out by a qualied company or by qualied persons which

have been specially trained in accordance with IEC 62271-4:2013, IEC 60480 and

IEC 60376 section 10.3.1 (as well as the Annexes A and B). In addition, it is imperative

that personnel are familiar with the physical principles of N2/ CleanAir / DryAir

(gas mixtures) and have the specic knowledge to perform gas handling and gas

measurements from IEC 62271-4:2013, ASTM D2029 - 97:2017 and the CIGRÈ - SF₆

Measurement guide (723).

Special operating conditions require further appropriate knowledge, e.g. of aggressive

media (ASTM D2284 – 11).

3.3 Personal protective equipment

The personal protective equipment is designed to protect the skilled personnel from

hazards that could impair their safety or health during work.When carrying out the

various tasks on and with the instrument, the skilled personnel must wear personal

protective equipment.

Follow the instructions displayed in the work area regarding personal protective

equipment!

The requisite personal protective equipment must be provided by the operating

company.

Wear safety goggles!

Safety goggles to EN 166, class 2.

They protect the eyes from ying parts during coupling or releasing of the

quick connections under pressure.

Wear protective gloves!

Protect hands from friction, abrasion, cuts or deep injuries and also from

contact with hot surfaces.
