Phase Loss Detection Using Current Signals: A Review

This paper discusses open phase faults, which can happen in a system grid-converter-motor drive, and measures to properly handle this type of fault. The authors provide classification algorithms used for the detection loss explain distinctive features each group methods. They review existing algorithms, are based on analysis current signals, discuss their pros cons suggest possible areas usage also propose one novel method phase, was developed low-cost systems with low resolution analog-to digital converters (ADC). mainly considers methods three-phase motors as most popular machines, however some be multiphase drives. share more than 20 years’ experience combined, area, obtained by developing industrial commercial drives, focus requirements IEC/UL 60730 safety standard, where phase-loss algorithm is essential parts control system.
