Microcomputer AC power tester (excluding computer)）中西器材 M411146

The microcomputer AC power tester is a comprehensive AC power analyzer that combines microcontroller technology with TFT color screen display. It can measure three-phase voltage, current, power, YIN number of power, cumulative JI quantity, and also perform harmonic analysis. At the same time, it also supports expansion, USB data (data printing) acquisition, and automatic measurement, making it convenient for users to save measurement data in real time. There are two measurement methods available: three item three line and three item four line. It is a testing instrument developed based on the characteristics of China's railways and the national standard GB/T12497-2006, suitable for use on the GUO railway in China. 1： Main performance indicators: 1. Basic test items: Three phase AC voltage Ua, Ub, Uc and voltage mean U, three-phase AC current la, lb, lc and current mean l, grid frequency F, active power Pa, Pb, Pc and three-phase total active power P, reactive power Qa, Qb, Qc and three-phase total reactive power 0, apparent power Sa, Sb, Sc and three-phase total apparent power S, power YIN, cos φ 1, cos φ 2, cos φ 3, cos φ 4 (cos φ 4 is the average power factor of the three phases), real-time display of voltage and current waveforms for each phase, and real-time display of vector diagrams for single-phase DA. Analyze the phase values and phase differences. Cumulative power consumption measurement (cumulative | time interval unit in minutes, cumulative total time unit in hours) Harmonic analysis: Measure the fundamental frequency, waveform distortion | rate, and various harmonic levels (20th harmonic) of each phase voltage and current. Print data: Built in printer, capable of printing measurement data during SUI. Can display and set the current time. An 8-inch color touch screen displays and calculates 11 parameters for the economic operation of the electric motor, as well as analyzes and calculates the operating conditions of the motor. It also measures 7 parameters for the working characteristics of the electric motor and calculates the cumulative power automaticallyThe capacitance for on-site compensation and the annual energy savings after compensation are stored in the instrument database for the economic operation test project Y、YR、J、J2、JR、JR2、JS、JS1、JS2、YX、YPZC、FX、FGX2、FO、JF03 Waiting for over 80 series of nearly 10000 types of motor parameters: model, rated power, rated voltage, rated current, rated efficiency, no-load current, no-load power, power YIN number.
