I. Product Overview
The three-phase electrical parameter analyser is a high-precision electrical measurement instrument designed specifically for quality control on production lines and laboratory research and development of motors, pumps, fans and electrically controlled equipment. It is compatible with three-phase three-wire and three-phase four-wire power supply systems, and is commonly used in conjunction with various comprehensive motor test benches and pump performance test benches to simultaneously collect electrical data. The device utilises high-precision data acquisition chips to simultaneously capture electrical parameters across all phases, ensuring stable data and high repeatability. It is capable of performing the full range of measurements required for factory acceptance testing, performance calibration, energy consumption analysis and fault diagnosis, making it an essential piece of equipment for quality control in electromechanical manufacturing enterprises.
II. Core Measurement Parameters: Capable of simultaneously acquiring all electrical parameters—both per-phase and total—covering the full range of testing requirements across the industry:
1.Basic Electrical Parameters: Three-phase voltage, three-phase current, frequency, phase angle, and phase sequence detection;
2. Power-related indicators: Active power, reactive power, apparent power, power factor;
3. Energy and efficiency: input electrical energy, motor input power, total efficiency of pump units, phase-by-phase losses;
4. Extended testing: 2nd to 50th harmonics, three-phase imbalance, voltage and current waveform recording;
5. Supporting calculations: automatically converts torque and rotational speed data to output power and overall operational efficiency.
III. Core Product Advantages
1. Ultra-high measurement accuracy and reliable data: Voltage and current measurement accuracy ≤ Class 0.1; low power measurement error; equipped with a true RMS sampling algorithm to prevent data drift under motor start-up surges and harmonic interference conditions, fully meeting high-precision factory acceptance test standards.
2. Three-phase synchronous data acquisition, user-friendly operation: Three independent, isolated voltage channels and three independent, isolated current channels; once wiring is complete, one-button activation initiates synchronous sampling, eliminating the need for phase-by-phase or sequential measurements; paired with the standard open-jaw current clamps, connections can be made quickly without disconnecting the main circuit, significantly reducing the testing time per unit.
3. Intelligent data processing with full traceability: A built-in data storage module automatically records each set of test data; the accompanying PC software supports real-time data upload, performance curve plotting, and the export and printing of reports in Excel or PDF formats. Product numbers and nameplate information can be customised to enable end-to-end traceability of production data, meeting the requirements for quality inspection records during factory audits.
4. Wide-range versatility, suitable for multiple equipment types. The voltage range covers standard power-frequency voltages from 0–500 V, whilst the current range can be expanded by replacing current clamps of different specifications. It is suitable for everything from low-power micro-motors to high-power industrial drive motors, coolant electronic pumps and fan modules, enabling a single instrument to cater for all production lines in the workshop.
5. Industrial-grade durability and protection, suitable for workshop conditions. The unit features a metal protective housing that is resistant to electromagnetic interference, dust and shock; a wide-temperature LCD display ensures clear visibility in both high- and low-temperature workshops; and automatic overvoltage and overcurrent protection ensures stable, continuous 24/7 operation with a low failure rate.
IV. Applicable Scenarios
Widely used in final inspection test benches for complete motors, fan motor test benches, comprehensive performance testing systems for electronic pumps, and test equipment for servo joint modules; suitable for quality control workshops and R&D laboratories in motor manufacturers, pump manufacturers, ventilation equipment manufacturers, and automation component enterprises. Used in scenarios such as 100% final inspection of finished products, performance calibration of new products, energy consumption comparison tests, screening for electrical faults in windings, and verification of measurement errors.
V. Supporting Services
The instrument supports integration with various customised test bench control systems, and software report templates can be customised according to the customer’s testing procedures. We provide full-unit calibration, operational training and long-term online technical support, as well as optional accessories such as multi-range current clamps and extended test leads on request.
