Determination of Parameter & Losses in a Single Phase Transformer by OC & SC Test

The Determination of Parameters & Losses in a Single Phase Transformer by OC & SC Test trainer from Glass Agencies is a laboratory training system developed to provide practical understanding of transformer characteristics and performance evaluation. This setup allows learners to determine the equivalent circuit parameters and measure losses in a single-phase transformer using open-circuit (OC) and short-circuit (SC) tests. It provides hands-on experience in analyzing transformer behavior under no-load and full-load conditions, converting theoretical knowledge into measurable results. 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 single-phase transformer, control switches, measuring instruments such as voltmeters, ammeters, and wattmeters, protective devices, and clearly labeled terminals for systematic connections. Insulated wiring and an organized layout support safe and efficient experimentation. Learners can perform the OC test by applying rated voltage to the primary winding with the secondary open, measuring voltage, current, and power to calculate core losses and no-load parameters. In the SC test, a reduced voltage is applied to the primary with the secondary short-circuited, allowing measurement of current, voltage, and power to determine copper losses and equivalent series parameters. The arrangement allows observation of transformer behavior under controlled conditions and helps students understand the effect of load and excitation on performance. Accurate instruments and high-quality construction ensure reliable readings and repeatable results, which are essential for academic study, performance analysis, and reporting. The structured layout simplifies wiring, improves visibility of components, and allows convenient connection of auxiliary measuring devices. This makes the trainer suitable for engineering colleges, polytechnic institutes, and technical training centers where electrical machines, transformers, and power systems are part of the curriculum. By translating theoretical concepts into practical experimentation, the system strengthens understanding of transformer parameters, losses, efficiency, and regulation. 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, connection accessories, and instructional guidance to facilitate installation, experimentation, and routine operation.
