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

The Measurement of Power in Single Phase Circuit by CT, PT & Single Phase Wattmeter from Glass Agencies is a laboratory training setup developed to explain accurate power measurement techniques used in electrical systems. This arrangement helps learners understand how current transformers and potential transformers are applied with a single phase wattmeter to measure power safely and effectively in circuits operating at higher current and voltage levels. The system allows students to study the role of instrument transformers in scaling electrical quantities to measurable limits while maintaining correct proportional relationships. The setup consists of a well-arranged panel mounted on a strong base, incorporating a single phase wattmeter, current transformer, potential transformer, switching elements, protective components, and clearly identified terminals. This configuration supports safe handling and systematic experimentation in academic laboratories. Learners can observe connections, note meter readings, and calculate actual power values by applying transformation ratios, thereby strengthening analytical understanding. The arrangement supports experiments under different load conditions, helping users study the effect of load variation on current, voltage, and measured power. Accurate transformer ratios and stable construction contribute to consistent readings and dependable experimental outcomes. The organized layout simplifies wiring, improves visibility of components, and allows easy connection of external loads and measuring instruments. This makes the setup appropriate for engineering colleges, polytechnic institutions, and technical training centers where electrical measurements and instrumentation are part of the curriculum. By translating theoretical concepts into practical observation, the system enhances understanding of power measurement methods, energy accounting, and metering principles used in real electrical installations. Compact dimensions allow convenient placement on laboratory benches without excessive space usage, supporting efficient lab management. The unit is supplied with necessary connection leads, fuses, and instructional guidance to assist with installation, operation, and routine experimentation. Each assembly is produced under careful inspection procedures to ensure stable performance during repeated academic use. This power measurement trainer reflects the commitment of Glass Agencies to supplying dependable laboratory equipment that supports structured learning, improves calculation skills, and builds strong practical knowledge in the field of electrical measurements and power engineering.
