The good continuity of service can be obtained if all the components of power systems can operate well in every situation and condition, either in normal or in abnormal condition. In abnormal condition, the protection system has an important role in detecting every disturbance and disconnecting the disturbed parts from the system. The power transformer is the main component in a substation. The disturbances in the transformer should be isolated so as not to disturb the system during distribution of the electric power to other load. The differential relay on the power transformer is a protection relay to detect internal disturbance. This paper discusses the setting and mismatch error of differential relay in substation of Central Duri at switchgear #3 at PT Chevron Pacific Indonesia (PT CPI).
