When designing ground-fault protection (GFP) for a power distribution system, you should always consider the nature of the power source. If the power source is from a separately derived system, you ...
Residential and commercial circuit breakers face three major challenges: detecting arc faults reliably, reducing false trips ...
An electrical arc flash can occur when someone is verifying the presence of voltage, checking the balance of current, operating a switch, inspecting an energized cable or bus connections during ...
To date, all Voltage Source Converters (VSC) used in HVDC networks are incapable of clearing faults on the DC side of the converter. “For most of the situations where such converters have been used so ...
Schematic view of a typical Smart Cable Guard setup with a monitored cable section spanning multiple RMUs installed in medium-voltage/low-voltage substations. Medium ...
Solid-state power controllers (SSPCs) are designed to replace mechanical circuit breakers, which work by tripping when the temperature of their internal sensors reaches a predetermined level (Fig. 1).
