Assessment of Voltage Unbalance Factor to Evaluate its Effect on Three Phase Induction Motor
2023 3rd International Conference on Emerging Frontiers in Electrical and Electronic Technologies (ICEFEET), 2023Firstly, this paper provides the fundamental understanding of voltage unbalanced (VU) and its adverse impacts on three phase induction motors (3-ΦM). Then, the voltage unbalanced factor (VUF), provided by IEC standard, has been considered to quantify the

The Impact Analysis of Various Unbalance Factors on the PCC Voltage Imbalance
2014 IEEE Electrical Power and Energy Conference, 2014Excessive voltage unbalance levels under normal operating conditions has become a power quality problem of concern in many power networks. Most available unbalance study only considers the three-phase three-wire power system and concentrates on the unbalance definitions, standards and effects.
