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 …

The degradation of AC filter (ACF) arresters in converter stations can be accelerated by the
frequent occurrence of unipolar polarity impulse currents during energization of ACFs …

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

En la presente investigación, se propone una metodología para solucionar la planificación
de la expansión de la transmisión (TEP) de un sistema eléctrico de potencia (SEP) a corto …

Pre-insertion resistor (PIR) is an important component of circuit breaker. The healthiness of
the circuit breaker (CB) depends upon that of PIR contact. With the increasing demand of …

Different from typical circuit breakers, breakers used to switch AC filters in convertor stations
have to operate frequently according to the real-time operation mode and daily load …

The pre‐insertion resistors (PIR) within high‐voltage circuit breakers are critical components
and warm up by generating Joule heat when an electric current flows through them …

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 …

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 …
