|Title:||Microprocessor-based system for identification of phase sequence and detection ofphase unbalance of three-phase ac supply|
|Keywords:||Microprocessor-based system;Phase sequence;Phase unbalance|
|Abstract:||A prototype detection system based on 8085 microprocessor / 8751 microcontroller has been developed for identificationof phase sequence and detection of phase unbalance. System principle compares self-generating code by hardware circuit withpre-defined specific codes corresponding to positive and negative sequences for successful match in each measuring cycle.System is also capable in detecting phase unbalance, if any. Rule based intricate software algorithm is developed and operateswithin a cycle. Processor generates signals for detecting phase sequence and phase unbalance up to a recommended value|
