1. Show on high-brightness,
high-definition, high resolution ratio 10.4"
(640*480) TFT color
liquid crystal display;
2. The system uses high-speed, high-accuracy digital
multiplier to measure all parameters s-
uch as active (reactive)
power, voltage, current, frequency, phase etc and
calibrates th-
em through software;
3. This device has no potentiometer, which protects
it from error change caused by transpor-
tation or other factors,
and increases stability and reliability of the system
greatly;
4. The system adopts the digital absolutely reactive
testing technology that is first inven-
ted in our country. This
technology makes testing under reactive research
a situation that
not influenced by voltage
and current unbalance, phase angle dissymmetry and
frequency ch-
ange. This technology
also increases the reactive accuracy rate up to
0.1% the first time
in our country.
5. Assure the power accuracy (0.1% or 0.05%) between
temperature of -20≧ to +40≧; test ele-
ctric energy in four
quadrants;
6. Able to equipped with 0.2 %5A transformer (including
split non-repeat errors, touching er-
rors, outside magnetic
field interference errors, angle errors and so on);
7. Can be attached with 20A, 100A, 500A, 1000A transformer
to directly measure low voltage g-
auging integrative errors
and CT rate ratio and angle accuracy with 5A transformer;
8. Voltage switches automatically from 30V to 480V.
Current input value is 5A;
9. Wide working electric source is 50~260V. when
researches 380v,it will make over voltage p-
rotection;
10. Identify three-phase three lines 48 kinds errors
and three-phase four lines 96 kinds err-
ors;
11. The hexagonal nomogram of any kind of line connection
is able to be used for line check
training, after showing
incorrect identification;
12. Able to measure the 2nd ~21st harmonic wave
of three-phase voltage and current, and save
all harmonic wave¨s data;
13. Able to show three waveforms of voltage and
current at the same time;
14. Provide error calibrating function, so that
it is convenient to calibrate errors, but it
needs password;
15. Update software through PC or Modem;
16. Save all testing data of 10000 watt-hour meters,
including working parameters, convenien-
tly for analysis;
17. Able to be attached with <PEC watt-hour meter
management system> software to realize a s-
ituation like that working
without paper;
18. Check single-phase, three-phase three lines,three-phase
four lines active and reactive i-
nduction type watt-hours
meter and electronic watt-hours meters(able to receive
impulse of
electronic watt-hours
meter) automatically or by hand;
19. Able to calibrate voltage, current, power, power
factor, phase and frequency of electrot-
echnical instrument and
transmitter by comparison;
20. Notebook style, light and convenient;
21. Stainless steel painting box, firmness and wear
well. |
