1.4.1
Structure and performance of the detector
Function principles
To determine the air-tightness of the controlled object and to localize the leakages, the
following routine should be followed. The controlled object is filled with SF6 gas or gas
mixture doped with SF6 .
The pressure inside the controlled object should exceed the atmospheric pressure by
0.5 atm . . . 5 atm. In case of leakages, the air around the leakage localization will have
increased concentration of SF6 molecules.
After pulling the trigger on the HHU handle, the air pump starts working and the air
sample is pumped inside the detector through a hand-held tool tip (flexible or telescopic).
This air sample is pumped through the pneumatic path of the detector and analyzed. The
laser-acoustic spectroscopy method is used for the determination of the SF6 molecules concentration. The acoustic waves are emitted in the gas probe due to absorption of the laser
radiation by SF6 molecules.
1.4.2
Structure of detector
The general scheme of the detector is presented in Figure 1.4. The intake (1) is connected
via adapter (2.1). to the HHU (2). The HHU (2) is connected to the main block (8) via the
combined pneumo-electric cable (4). The air sample is pumped through the intake (1), HHU
(2) and a cable (4) into the main unit pneumatic path. Inside the main unit, the air passes
the entrance filter (8.3) and then is pumped to the optical-accoustic detector (OAD) (8.10).
After the OAD, the air probe continues to the acoustic muffler (8.9) which suppresses the
air flow pulses appearing due to the function of the air pump (8.2).

Figure 1.4: Schematic structure of the SF6 LaserGasTest.
Entrance air filter (8.3) prevents solid and liquid aerosol particles on the optical elements
in the pneumatic path of the detector. The exit protection valve (8.1) is located at the end
of the pneumatic path.
The determination of the SF6 concentration in the air sample is performed in the OAD
(8.10). The laser radiation (8.4) excites an acoustic wave which is detected by OAD microphones (8.10). The electric signal from the microphones is transmitted for further processing
to the main board (8.11). The main board (8.11) processes the signal of the OAD microphones and controls the indicator panel (8.6) that indicates the main parameters and modes
of the device function. It also controls air pump (8.2) and performs the control signals of
the laser power supply (8.5).
The indicator assignment is presented in the Table 1.6.
The power supply system of the detector consists of rechargeable battery (8.7) and AC
power supply (8.8). Battery (8.7) supports the autonomous function of the detector. AC
power supply (8.8) supports the function from the mains and recharge of the battery (8.7).

The battery status can be checked inside the main unit when the cover is open, by
controlling the indicators on panel 10:
• in case if the detector is working from ∼220 V supply and the battery is fully charged,
the indicators POWER and EXTERNAL will be on and the indicator BATTERY will
light green
• if the detector is working from ∼220 V and the battery is charging, the indicators
POWER, EXTERNAL and CHARGE will light
• if the detector works from the battery, indicators POWER and BATTERY will light;
color of the BATTERY indicator depends on the charge of the battery: at a working
charge level green, at low charge level red.
ATTENTION!
To avoid damage of the LEMO plug contacts, one has to pay special attention during
the connection of the cable to the HHU and main device. Please follow the routine below:

IMPORTANT!
To improve the measurement precision in case of low SF6 concentrations (<100 ppm)
during the long-term measurements it is recommended to restart the detector by double
pressing the Start trigger.
ATTENTION!
In case of long-term measurements of high SF6 concentrations (>100 ppm), gas particles
can be absorbed by the pneumatic tract of the detector. It is recommended to place the
detector in the area with clean air and keep it running in the measurement mode witin a
time equal to the measurement time of the high SF6 concentrations. This procedure ensures
cleaning of the pneumatic tract from the gas rests.

2.3.1
General instructions
To start work with the detector one has to follow the routine as described in chapter 2.2.3
above. Parameters and working modes can be set with the navigation buttons browsing the
respective menus if needed.
The graphic menu of the HHU is designed to set the parameters and working modes of
the detector. Optimal parameters and working modes depend on the measurement goals
and parameters of the tested objects. The map of the navigation menu is presented in
appendix B. Navigation through the menu is done by the navigation buttons according to
1.7.
It is possible to use the detector without the handpiece, but in this case, the control and
measurement results storage has to be provided through the PC.
2.3.2
Description of the measurement methods
The detector is used for the detection of the SF6 leakages from the gas filled
devices according to IEC 600682-17 providing measurements at the
atmospheric pressure.
• tester
• collection at the atmospheric pressure
During the leakage detection with the detector test object has to be filled with SF6
or the air-gas mixture with at least 1 % of SF6 at an excessive pressure of 1 atm . . . 6 atm
according to the limitations of the tested object. Leakage search is performed by moving
the HHU intake along the controlled areas of the tested object. Due to the low mobility
of SF6 molecules, the concentration increase is observed at the leakage location. When the
HHU tip approaches the leakage location, the air with SF6 molecules is pumped inside the
pneumatic path of the detector. Localization succeeds on the maximum concentration of
the SF6 as shown on the display or repeated by maximal frequency of the sound signals.
For the leakage detection by means of the sample collection at the atmospheric pressure
the controlled object is filled with the SF6 air-gas mixture with at least 1 % of SF6 . The
object is filled with 1 atm . . . 6 atm excessive pressure according to the technical parameters
of the object. The tested object is placed in a bag, or a chamber filled with air. An air fan
is placed inside the chamber to mix the air with SF6 gas, that comes out from the tested
object in case of leakage.
The HHU intake is inserted into the bag or chamber. The concentration of the SF6 gas
will increase proportionally to the time of the test object observation in the chamber.
The density of the SF6 gas is d=6.139 g/l at 20 ◦C. So the volume concentration of 1 ppm
is equal to concentration of 6.139 µg/l.
Integrated leakage of SF6 from the tested object is defined by the equation 2.1:
M = 0.0538 × ∆C × (VC − VO − Vf )/∆T
(2.1)
where M is an integrated leakage of the SF6 gas in gramms/year, ∆C SF6 concentration
increase in ppm, VC internal volume of the chamber in liters, VO outer volume of the tested
object in liters, Vf outer volume of the fan in liter, ∆T is the time between the measurements
in hours.
To transfer the volume concentration, measured by the detector, in ppm units (Mio-1 )
into the concentration, measured in g/l, the equation 2.2 is used:
∆C(g/l) = ∆C(ppm) × 6.139 × 10−6
