1. This device
has rational design and nice look. Its hanging frame
and table frame are all
made of special aluminium
alloy materials. The table plate is consist of fire-proofing
a-
nd heat proof fiber materials,
which makes the whole device has gentle color, harmonic
p-
roportion, solid configuration,
unique craftsmanship and nice looking.
2. This device combines specialized key-board operation
and PC operation together, rather c-
onvenient to use. The
key-board has liquid crystal display so that the
operation of this
device is clear at a
glance and the operation is fairly easy. PC controls
software, well-
bedded, nice interface,
and flexible use.
3. High automation. When measure watt-hour meter,technicians
only need to hang the device w-
ell, adjust light and
electricity sampler properly and set the parameters
correctly, all
of the testing items
(including pre-heat, creeping test, starting test,
standard error t-
est, intrinsic error
test) are controlled by PC, completed once. Calibrating
procedure c-
an be compliance with
national regulation or defined by user himself.
4. Light and electricity sampler is able to realize
three-dimensional adjustment,not only s-
ample the rotating signal
of rotary type watt-hour meter, but also receive
the strobosco-
pic signal of electric
watt-hour meter.
5. Error dealing system able to receive signal from
light and electricity sampler, output i-
mpulse of install type
electronic meter, high-frequency impulse signal
from standard watt
-hour meter and so on.
6. Able to calibrate simultaneously similar type
(phase wire, rated voltage, labeled current
are the same) and watt-hour
meters with different constants (three types of
constants li-
mited).
7. Automatically localize the black sign of rotary
type watt-hour meter’s turntable, in or-
der to make creeping
(starting) test conveniently.
8. Able to add 2nd ~21st harmonic waves on the fundamental
wave.Amplitude value and phase c-
an be set according to
different requirements. Moreover, it is able to
make harmonic ana-
lysis on the output capacity
and draw waveform as well.
9. High stability, good reliability and large output
power. Voltage (current) circuit is ab-
le to take any load.
10. Advanced error testing, localizing, protecting
and alarming function, in case of damage
caused by man-made wire
connection and operation failure.
11. PC management software processes perfect functions
such as report forms printing, mathe-
matics statistics, assets
maintenance and so on;
12. Testing platform has several phase size such
as 3、8、12、16、24、48, it is able to simu-
ltaneously test meters
with different constants. |
