Distribution Transformer's Insulation Thermal Coefficient Measurement under Unbalanced Operation
Physics and Technical Sciences, 2013A reliable and endless supply of electricity is highly dependent on good operation of distribution transformers. A huge number of customers are directly supplied via any of the transformers. Loading of the transformers under unbalance conditions is an important factor that influences the life of their insulation.

Unbalanced Operations of Three-Phase Machines with Damper Circuits
IEEE Transactions on Power Apparatus and Systems, 1969A study on unbalanced short circuits of three-phase machines with additional field circuits is discussed, and a detailed solution for the case of a double-line-to-ground short circuit of a salient-pole synchrenous machine is offered. By mathematical analysis, new and complete transient solutions for short-circuit currents, torque, and open-phase ...

Characteristics Analysis of Power Capacitor with Unbalanced Voltage Operation
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, 2008In the three phase four wire system, voltage unbalance caused by the unbalanced load operation, gives rise to current unbalance and de-rates by the increase of machine`s loss and eventually enlarges power capacity and besides has a bad effect on power quality.

Disturbance-rejection control for unbalanced operation of microgrids: Invariant-set approach
ISA TransactionsIn microgrids, voltage imbalance control is crucial to preserving the required level of power quality. The article presents a tracker design that mitigates the unbalance in the microgrids. The proposed microgrid model includes positive and negative sequences, whereby the positive sequences are controlled, and the negative sequence is treated as an ...
