Posted at: Offers to Sell and Export | Posted on: Tuesday 13 December 2011 2:50 am | Poster last visit: Monday 21 March 2016 |
Product Description:
It meets the whole requirements of GB/T1459～93 to test the virtual value, and positive, reverse
and zero sequence component of current and voltage
Measuring area: content of voltage harmonic, distortion factor of phase-angle and current voltage
Virtual value of current harmonics, distortion factor of phase-angle and total voltage harmonics
Range of measuring harmonics: fundamental wave -51times harmonics
Way of input signals: voltage, current, phase
Print: printed three-phase waveforms, statistic of the testing results, automatic printed three-phase results.
The key technical indexes:
1．Way and range of input signal
A．Three-phase voltage and three-phase current
B. voltage test range: 10-240V（or 20-400V）
C. current test range: 0.05-6A (or0.1-12A)
D. tracking range of fundamental harmonics frequency
2. Input impendence: voltage side≥200kΩ, current side≤20mΩ
3. Measuring accuracy: measuring error of fundamental: ≤0.5%
4. Measuring times of harmonics: 5-51
5. Statistical times：5～96 times are choiceable
6. Timing space of orientation in time：0～999 minutes are choiceable
7. setting range of continuous limited number：0～999
8. time of equipments’ power supply source：220V±15%；50Hz±5%；THDu±≤8.0%; 20VA
