Abstract

Switching transients, generated during energizing and de-energizing operations of capacitor banks can damage the capacitor itself and other sensitive components in the network. To reduce such effects, this study suggests a High Pass Filter (HPF) transient limiter to provide low impedance at the instant of capacitor energizing, thus, allowing the switching transients to decrease effectively. In addition, this study covers different operational cases to find suitable methods or techniques that can be used to limit the impact of capacitor transient switching. The simulation which was based on an electrical network model in low voltage (LV) power systems (0.415 kV) was modeled using Power System Computer-Aided Design (PSCAD) software, focused on the peak transient magnitude, event duration and switching frequency. The results are presented in detail. The outcome of this study can serve as an essential guidance for manufacturing technologists as well as electrical engineers in addressing and developing capacitor banks, thus solving transient switching issues for low voltage systems.
