Product Description

 

Product Interview:

JH8000 three-phase electric meter field calibrator is a portable device specially designed and developed for field calibration of single-phase, three-phase active and reactive induction as well as electronic electric meters and other kinds of electrical instruments. It is widely used in electric power, metallurgy, chemical industry, tobacco, textile, railway, shipping, property and other industries. It provides a convenient solution for the power measurement department to perform meter error calibration on site without power cut or removing the electric meter and for the power inspection department to verify the illegal acts of stealing electricity.
This meter is mainly used to calibrate the errors of electric energy meters, check whether the wiring of metering devices is correct, check the transformation ratio and polarity of current transformers used for metering, and measure the electric power quality of users (including voltage harmonics, current harmonics, total harmonic distortion, voltage balance, etc.).

 

 

Main Features:

1. 5-inch TFT LCD screen (resolution: 800×480)
2. English and Chinese display.
3. Accurate measurement of voltage, current, active power, reactive power, phase angle, power factor, frequency and other electric parameters. It can be used to calibrate three-phase three-wire, three-phase four-wire, single-phase active/reactive electric energy meters.
4. Accurate measurement of primary current and secondary current, transformer ratio and angular difference of low pressure CT
5. Visual display of vector diagram of three-phase voltage and current. It has144 kinds of wrong wiring diagnosis functions (48 kinds of three-phase three-wire, 96 kinds of three-phase four-wire), along with an accurate and clear description of the error message. Corresponding correction coefficient would be given according to the error message.
6. Support three ways for electric energy meter calibration : photoelectric, manual, pulse
7. Support the running test of electric energy meter, and investigate and punish the stealing of electricity by changing nameplates and wheels.
8. Barcode scanner can be used to scan the identification number and user information of the meter being measured.
9. The real-time waveform of voltage and current of each phase can be displayed to judge whether the quality of voltage and current is good or not.
10. 2~50 times harmonic detection can be carried out and display the content or amplitude of each harmonic. The total harmonic distortion can be calculated automatically and displayed by histogram.
11. Three - phase imbalance can be detected and displayed.
12. It can store 9999 history data. Data can be exported through USB flash disk, or uploaded to PC through communication port.
13. Accuracy of current, voltage, active power, active energy: level 0.05 (type A), level 0.1 (type B).
14. Two modes are available: power adapter and battery powered. The built-in lithium battery can work continuously for more than 8 hours.
15. It has RS232, USB Host, USB Device, LAN interface, WiFi(optional) and other communication interfaces.
16. Built-in micro printer for printing test data on site is available .
