Alternating current power supplies and rolling stock with 25 kV (50 or 60 Hz) and 15 kV (16.7
Hz) traction systems do not have the characteristics and behaviour of a typical three‐phase …

Residual magnetic flux can cause significant problems in electric power system operation if
not taken into consideration. The laboratory setup and experimental procedure for …

Switching transients arises due to random switching of power apparatus results in
degradation of thermal and dielectric health of equipment and system as a whole. Controlled …

A new controlled Single-Phase Auto Reclosing (SPAR) technique for Shunt Reactor
Compensated Transmission Line (SRCTL) in electrical energy systems is presented in this …

Microgrids with high penetration of photovoltaic (PV) resources are becoming more common
in the energy infrastructure landscape including islanded microgrids occurring in rural areas …

In this era, smart grid technologies enable efficient and reliable switching of the power
transformer to optimize energy flow and improve overall system performance. Hence, in …

Pre-insertion resistors (PIR) are critical components for suppressing the closing inrush
current and operating overvoltage during the closing process of the circuit breaker. And it is …

Previous studies mainly focused on the behaviours of single‐break vacuum circuit breakers
(VCBs) in switching capacitor banks. The prestrike characteristics of double‐break VCBs …

Controlled switching of capacitor banks is an effective way to suppress the inrush current
during capacitive-making operations. The objective of this paper is to determine the …

The pre-insertion resistor is used to suppress closing inrush current and overvoltage.
However, it is not uncommon for the pre-insertion resistor to explode or break down in the …
