Abstract :
Fast and accurate measurement of real power is indispensable for power system monitoring and control, protective relay systems and fault recording systems. Taking advantage of the accuracy and simplicity of the Hall effect based sensor and powerful data processing and logic control functions of a microprocessor, a microprocessor based fast real power measurement device has been developed. A series of tests were conducted in a physical simulation laboratory to demonstrate its capability in measuring active power in balanced and various unbalanced conditions
