“…In some cases, they may also be used to maintain sustained short-circuit current through a cable that has developed an intermittent fault to enable fault location. Several devices to limit the fault current have been developed including electronically controlled fuses, tuned LC circuits, thyristor-controlled series reactors, solid-state fault-current limiters based on resistors/inductors switched by gate turn-off thyristors (GTOs), and superconducting fault-current limiters [1]- [6]. Some of these devices, such as the electronically controlled fuses, are of a single shot design.…”

“…Following an operation, the supply to the load is lost until the device is replaced. Other devices such as tuned LC circuits and those which limit the fault current by inserting a fixed impedance in the circuit are usually sensitive to the network condition (e.g., the short-circuit level) and fault location [2]- [6]. Fast current interrupting devices, such as fuses or solid-state circuit breakers, are only useful for certain applications, such as the bus-tie location or for the protection of single loads.…”

Abstract-This paper describes the development of a solid-state fault current limiting and interrupting device (FCLID) suitable for low-voltage distribution networks. The main components of the FCLID are a bidirectional semiconductor switch that can disrupt the short-circuit current, and a voltage clamping element that helps to control the current and absorb the inductive energy stored in the network during current interruption. Using a hysteresis-type control algorithm, the short-circuit current can be constrained according to a predefined profile. Insulated-gate bipolar transistors and diodes are used to construct the semiconductor switch. Varistors are used as the voltage clamping element. An effective method is adopted to improve the current sharing between parallel varistors in order to provide the required capability of energy absorption. An overall protection scheme for the FCLID is described. A prototype FCLID for 230-V single-phase, or 400-V three-phase, applications is developed and tested. Analyses and experiments are carried out to define the stresses that the main components in the FCLID are subject to. The results show that the developed prototype is capable of limiting a 3-kA prospective short-circuit current to 120 A for a period of 0.8 s, without exceeding the thermal limits of the chosen switches and varistors.
