There are many types of acoustic sources in the ultrahigh voltage (UHV) substation. The
acoustic signals of UHV shunt reactors obtained by direct measurement include many other …

Various overvoltage mitigation schemes were used in literature in suppression of switching
overvoltages in wind farms. However, the evaluation of how the effectiveness of these …

In an offshore wind farm, a high‐voltage switchgear interruption in an offshore substation
creates a high‐frequency, high‐amplitude overvoltage that can cause severe …

Mitigation techniques associating vacuum circuit breakers (VCB) were proven highly
effective in reducing switching overvoltages (SOV) in wind farms. However, the structure of …

It is important to determine the transient stresses at large power transformer winding
terminals because this transient stress may induce power transformer failure. When a …

Power grid modernization is often associated with new projects that imply the transmission
network expansion, where transient overvoltages related to energization maneuvers must …

This paper includes a computer simulation of switching transient overvoltages during the
disconnecting of shunt reactors (SR). Based on the results of the transient simulations, two …

This paper investigates the impact of grading capacitors on transient recovery voltage (TRV)
during shunt reactor switching in high voltage systems, considering different levels of current …

Shunt reactors are frequently installed at the end of a 500 kV double circuit extra high
voltage transmission lines (EHVTL) to help overcome the voltage rise caused by the long …

The vacuum current breaker (VCB) is wildly used in power system, especially in levels of
medium or low voltage. However, the accurate modeling method of VCB considering high …
