Perform the 2nd ~ 51st harmonic analysis on the measured signal, and test the total harmonic distortion rate, the content of odd and even and each harmonic. Press "3 harmonic" key, and the interface displays as follows: Press [←→] key to turn pages. Press [F4] to sort. Press [F1] key to measure A phase voltage and current harmonics. Three-phase energy meter field calibratorPress [F2] key to measure B phase voltage and current harmonics. Press [F3] key to measure C phase voltage and current harmonics. Press [F5] to switch to digital mode. The instrument can measure 2nd ~ 52nd harmonics, show harmonic spectrums and give out the percentage content of each harmonic. Explanation to name: The content of nth harmonic voltage is expressed as HRUn. Total harmonic distortion of voltage harmonic (THDu) and total harmonic distortion of current harmonic (THDi) are defined as, respectively THDu=(UH/U1)×100% THDi=(In/I1)×100% Harmonic order - refers to the multiples of fundamental wave frequency, relative to fundamental wave. If the frequency of mains supply is 50Hz, the 2nd harmonic is 100Hz AC component, the 3rd harmonic is 150Hz AC component and so on. Harmonic influence Harmonic pollution to power grid is becoming more and more serious, so the harm caused by harmonics can not be ignored, mainly reflected in: 1. Greatly increasing the chance of resonance in power grid, thus causing the risk of accidentsThree-phase energy meter field calibrator --- User Manual --- --- --- 37 arisen from very high overcurrent or overvoltage; 2. Increasing additional loss, and reducing the efficiency of power generation, transmission and power equipment and the equipment utilization; 3. Increasing the losses to electrical equipment (rotary motors, capacitors, transformers, etc.), accelerating the insulation aging, and thus shortening the service life; 4. Leading to the metering and measuring instruments (such as: energy meter) not to give correct instructions or measurement; 5. Interfering with the communication system, lowering down the quality of signal transmission, disturbing the normal transmission signal, and even damaging the communications equipment. 3.7 Time Settings 1. Press [7] to enter into the time settings interface; 2. Input time, and press [Enter] and the settings take effect. 3.8 Data Query Query means to inquire the calibration records, line inspection results, and fundamentalThree-phase energy meter field calibrator --- User Manual --- --- --- 38 frequency error data stored in the instrument. Operating steps: 1. Press [Query] to enter into the calibration data query interface as shown in the figure below: Store the data by date, and the meter calibration data within the same date are stored in a folder named for the date. 2. Press [Enter] key to view the calibration record on the date. 3. Press [Enter] to view the data details. Note: if the calibration task you want to find can't be found on the current interface,Three-phase energy meter field calibrator --- User Manual --- --- --- 39 search by turning pages through [← →] key. Press [F5] to delete the data of the current date.
