With the increase in penetration of power electronic converters in the power systems, a
demand for overcurrent/overloading capability has risen for the fault clearance duration. This …

This paper presents a traveling-wave-based fault location method for two terminal
transmission lines using unsynchronized current measurements from intelligent electronic …

Increasing renewable penetration and grid modernization initiatives are having a significant
impact on the operating and fault characteristics of distribution systems. As a result …

When faults occur in the microgrids, high frequency transients will be superimposed on the
system currents and voltages. The magnitude of those transients will attenuate as it …

Ultra-high-speed line protection is becoming a reality today, giving the industry a way to trip
line faults in a few milliseconds. One relay described in this paper that uses time-domain …

Differential protection is widely used for transmission lines, but its performance is affected by
distributed capacitance current and current-transformer (CT) saturation. Travelling-wave …

Timely detection and classification of faults on transmission lines are crucial requirements
for maintaining a reliable power supply to consumers. Rapid fault detection demands the …

This paper presents a new method for fault classification and location based on the Discrete
Wavelet Transform decomposition and signal reconstruction-a type of Multi-Resolution …

This paper presents a protection scheme for alternating current transmission lines based on
the traveling wave propagation. The analyzed protection scheme uses measurements in …

We look back at the history of distance protection, explain the first principles, and discuss
why our industry settled on designs we know and appreciate today. We look at why, after a …
