Measurement of Power in 3 Phase Circuit by CT, PT & 3 Phase Wattmeter

The Measurement of Power in 3 Phase Circuit by CT, PT & 3 Phase Wattmeter from Glass Agencies is a comprehensive laboratory training setup developed to explain power measurement methods used in three phase electrical systems. This arrangement enables learners to understand how current transformers and potential transformers are applied along with a three phase wattmeter to measure power accurately in circuits operating at elevated voltage and current levels. The system allows students to study the scaling of electrical quantities through instrument transformers while maintaining proportional relationships between primary and secondary values. The setup is assembled on a rigid and neatly finished base panel that includes a three phase wattmeter, matched current transformers, potential transformers, selector switches, protective elements, and clearly marked terminals. This configuration supports secure handling and organized experimentation in academic laboratories. Learners can perform connections, record meter readings, and compute total power by applying appropriate transformer ratios, helping strengthen analytical and calculation skills. The arrangement supports testing under balanced and unbalanced load conditions, enabling users to observe changes in current flow, voltage levels, and measured power across phases. Accurate transformer ratios and stable construction contribute to consistent readings and dependable experimental results. The structured layout simplifies wiring, enhances component visibility, and allows convenient connection of external loads and auxiliary measuring instruments. This makes the setup suitable for engineering colleges, polytechnic institutes, and technical training centers where electrical measurements, instrumentation, and power systems are included in the syllabus. By converting theoretical concepts into practical observation, the system improves understanding of three phase power measurement techniques, energy distribution principles, and industrial metering practices. Its compact physical form allows easy placement on standard laboratory benches without excessive space usage, supporting efficient laboratory organization. The unit is supplied with necessary accessories, connection leads, protective fuses, and instructional guidance to assist with installation, experimentation, and routine handling. Each assembly undergoes careful inspection to ensure stable operation and consistent output during repeated academic use.
