Introduction This article helps you to understand, how shift factors are considered and applied while performing protection and coordination study. This article mentions about applying shift factor for Line-to-Ground (L-G) fault on transformer secondary side. To understand the shift factor
Load Flow Studies: One of the most common computational procedures used in power system analysis is the load flow calculation. The planning, design, and operation of power systems require such calculations to analyze the steady-state performance of the power system
Causes of Phase Voltage Unbalance Most utilities use four-wire grounded-wye distribution systems. This is to connect single-phase distribution transformers to phase-to-neutral to supply single-phase loads, such as residences and street lights. Variations in single-phase loading cause the currents in the
This article provides a broad classification of the causes and impact of power quality problems that may occur on a power system, some typical causes of them and the potential impact on equipment. The electricity supply waveform, often thought of
Introduction A common practice is to ground all types of generators through some form of external impedance. The purpose of this grounding is: to limit the mechanical stresses and fault damage in the machine to limit transient voltages during faults
