Measurement of Power in Three Phase Circuit by Two Wattmeter Method

The Measurement of Power in Three Phase Circuit by Two Wattmeter Method trainer from Glass Agencies is a laboratory training system developed to provide practical understanding of power measurement in three-phase circuits. This setup allows learners to study the application of the two-wattmeter method for both balanced and unbalanced loads, enabling accurate determination of active power, phase currents, and voltages in three-phase systems. The system provides hands-on experience in connecting wattmeters, measuring line and phase parameters, and analyzing power readings, converting theoretical concepts into practical observation. The trainer is mounted on a sturdy and well-finished base panel to ensure stability and safe handling during repeated laboratory experiments. It includes a three-phase supply arrangement, load connections, two wattmeters, voltmeters, ammeters, control switches, protective devices, and clearly marked terminals for organized wiring. Insulated wiring and a systematic layout support safe experimentation and ease of operation. Learners can perform experiments by connecting the three-phase load, measuring line and phase currents and voltages, recording wattmeter readings, and calculating total active power. The setup allows analysis of power factor, load type, and phase sequence, helping students understand the effects of balanced and unbalanced loads on power measurement. Accurate instruments and high-quality construction ensure reliable readings and repeatable results, which are essential for academic evaluation, performance analysis, and reporting. The structured layout simplifies wiring, enhances component visibility, and allows convenient integration with auxiliary measuring devices or external loads. This makes the trainer suitable for engineering colleges, polytechnic institutes, and technical training centers where electrical measurements, three-phase systems, and power studies form a key part of the curriculum. By translating theoretical knowledge into practical experimentation, the system strengthens understanding of three-phase power measurement techniques, load behavior, and wattmeter application principles. Its compact design allows placement on laboratory benches without occupying excessive space, supporting organized and efficient laboratory work. The unit is supplied with necessary leads, load accessories, and instructional guidance to facilitate installation, experimentation, and routine operation.
