A differential is a small change in a variable that affects the output or result of a system. It's often used in protection systems to detect and respond to changes in the system's behavior, such as abnormal current or voltage levels.
Differential protection involves comparing the actual values of the measured variable to a reference value. Any significant difference between the two values indicates a potential issue with the system. For example, if the current measured at a particular point in the power system is significantly higher than the normal operating range, it could indicate a fault or short circuit.
By continuously monitoring and analyzing the differential values, protection systems can automatically detect and isolate faults or disturbances, ensuring the stability and safety of the power system
