January 24, 1996 - Levine Lectronics and Lectric

Ground faults on the transformer secondary are seen as ground faults on the primary since the zero sequence (neutral) current passes directly through the transformer, making relay protection difficult. With a delta-wye transformer, the secondary ground faults do not cause zero sequence current to flow in the primary circuit.

MITIGATION OF FLICKER AND VOLTAGE FLUCTUATIONS | …

Sep 18, 2011· There are several techniques available for Flicker Mitigation.However, since flicker is caused by voltage fluctuations, these methods should be based on reducing such power quality phenomenon.

Concepts of Reactive Power Control and Voltage Stability

appliances and other motorized loads, as well as your electrical infrastructure. Since the current flowing through your electrical system is higher than that necessary to do the required work, excess power dissipates in the form of heat as the reactive current flows through resistive components like wires, switches and transformers. Keep in

Power Quality - Quality starts with the voltage.

Quality starts with the voltage Solutions for improving voltage quality and grid efficiency. A stable energy supply with a standard-compliant voltage is an important economic success factor for all appliions and is often a prerequisite for grid connection.
