Abstract |
|
Digital protection of power transformer is critical. It has various advantages over conventional protection schemes. Digital protection is carried out for fast and reliable operation of protective schemes for the protection of power transformers. Discrimination between inrush current and internal fault was simulated by designing Digital differential relay in MATLAB SIMULINK to observe the performance of relay. Amplitude and harmonics in the primary and secondary side current of transformer have been compared to get the results. Total Harmonic Distortion (THD) was analyzed by various tests to evaluate performance and operation of the relay and the results were obtained. |
