“…Extensive overhead-cable networks are then created, in which cable sections are exposed to overvoltages arising from arc faults in overhead sections. To limit the overvoltage effects, overvoltage limiters (surge arresters) are commonly used [18,19] or the Petersen coil is shunted or replaced by a resistor with a current not less than the total ground capacitive current of the network [20].…”

The article presents the results of research in the field of limiting the effects of overvoltages and improving the conditions for the self-extinguishing of transient faults in medium voltage networks with earth fault current compensation. The aim of the research was to estimate the level of overvoltages generated by an earth fault during re-ignition of the electric arc and to assess the possibility of reducing them by increasing the attenuation of the earth fault circuit. The results of the conducted tests show that to increase the attenuation, which ensures a significant effect of limiting such overvoltages, it is enough to change the way of operation of the devices forcing an additional active component of the earth fault current (AWSCz/ACFA). In Poland, such devices are commonly used to improve the effectiveness of earth fault protection. It was also found that the proposed solution enables accurate tuning of the Petersen coil in networks with natural asymmetry of earth capacitances. Therefore, changes in the operation of AWSCz/ACFA devices may have a beneficial effect on the limiting the effects of repeated ignitions during earth faults and, at the same time, enable the accurate tuning of the Petersen coil and increase its ability to extinguish arc-fed faults. Research and theoretical analysis of the issue were carried out on the basis of data characterizing the parameters of the earth fault circuits of the real 15 kV network.

“…In addition, a series capacitor (C s ) is employed to provide conditions for the occurrence of ferroresonance phenomenon. In order to investigate the proposed circuit from this viewpoint, the following relations can be considered: where N stands for the turns ratio, φ is the amount of the flux, IL is the amount of ferroresonance current, a and b are constant, q is a number that causes the amount of ferroresonance current to be nonlinear and varies between 2 and 13 [31]. By applying KCL in Figure 8:…”

This paper introduces a multifunctional protective system to mitigate more likely threats in power networks. The proposed device can cope with short circuit current, voltage sag, or swell and dangerous overvoltages due to ferroresonance by elaborate switching in its unified structure. The switching is in fact the main key for playing among the functions and altering the structure. Since the switches receive the control system’s commands based on what happens in the network, an intelligent controller has to be designed to interpret four operating modes and activate the correct function. Following the activation command, the structure is customized through switching action and the network is equipped with the corresponding protection function. The proposed scheme by employing minimum components and therefore achieving significant saving in costs can meet all expectations satisfactorily. Moreover, the control system’s performance is examined by a set of numerical simulations in a Matlab/Simulink environment. The obtained results show that the proposed device is feasible and successfully performs all three functions independently.

“…In Reference 21, this BFCL with multilevel switching strategy is proposed to reduce the fault current level. In Reference 22, a dual‐function BFCL is proposed to control the ferroresonance overvoltage in distribution systems. In Reference 23, a voltage‐adaptive multiresistor BFCL is proposed to compensate the voltage sag in wind power plants.…”

This article presents an adaptive voltage sag compensation scheme by using interline bridge-type fault current limiter (IBFCL) in radial distribution network to protect customers connected to the point of common coupling (PCC). Regarding voltage sag depth, the IBFCL provides a variable resistor in faulted feeder to compensate the PCC voltage at the acceptable level under whole voltage sag condition. To achieve this, a new control system based on the deviation of voltage sag at PCC bus is designed and implemented to the IBFCL. To check
