A quench detection device (or method) is provided that receives real-time information of concurrently monitored electrical characteristics of a high temperature superconducting (HTS) device, or any superconducting material, device, or system including low temperature superconductors, during operation. The quench detection device determines whether an electrical threshold is satisfied based on the received real-time information. The quench detection device detects a quench condition if the electrical threshold remains satisfied over a predetermined period of time or a predetermined successive number of times. If a quench detection is detected, the quench detection device sends a signal to terminate the operation of the HTS device.
