A quench detection system for a fault current limiter (), in particular, a high temperature superconductor fault current limiter, making use of a differential protection relay wherein in fault event the differential protection relay operates a triggering mechanism of a circuit breaker (), thereby opening the electrical circuit and interrupting power supply to downstream components, and a method for quench detection wherein the magnitude of voltage drop during quench is converted to a current signal being proportional to the voltage and which is monitored by the differential protection relay.

Quench detection system for a superconductor fault current limiter

A modular design of a fault current limiter includes one ore more current limiting unitswith one or more superconducting elementsand where standardized current limiting unitsand standardized modular insulation housingscan be used for modular design of a fault current limiter.

Current limiting device

The present invention relates to a quench controlled high temperature superconductor component wherein at least one depression is provided in a surface of the component resulting in a reduced wall thickness, and, wherein an electrical shunt is applied into the depression.
