    This paper presents the analysis on the characteristics of the IED based busbar protection systems based on the practical scheme designs. Any faults on the substation busbar mostly result in critical problems for system operation. Therefore, applying proper busbar protection scheme is very important. The types of busbar protection systems applied to the substations nowadays are normally high impedance scheme using OCR IED(Intelligent Electronic Device), dedicated high impedance busbar protection IED using current detection element scheme and IED based low impedance centralized & de-centralized scheme. The use of low impedance based busbar protection scheme becomes prevalent but the high impedance busbar protection schemes are still used since each type of busbar protection schemes has its own advantages and disadvantages. The proposed application guidelines of each scheme are presented using manufacturer data with detailed scheme analysis and comparison on design benefits.
