The ETB-229 Schering Bridge Trainer is a high-precision experimental setup used for the measurement of unknown capacitance and dielectric loss in capacitors. This model demonstrates the practical application of the Schering Bridge method, widely used in electrical engineering for testing insulating materials. The trainer includes a built-in power supply, calibrated dials, and terminals for easy connection of circuit components. Ideal for academic laboratories, it helps students understand AC bridge theory, balance conditions, and loss angle calculations in dielectric materials.
