What is NTC Thermistor? (Types, Applications & Advantages)
What is NTC Thermistor- The term "NTC" is the abbreviation for "Negative Temperature Coefficient". In NTC thermistors, the resistance decreases as temperature increases, so they are resistors with a negative temperature coefficient. In addition to serving as resistive temperature sensors, they are also used as current-limiting devices.

Thyristor based bridge‐type fault current limiter for fault …
The SCRs are in series with the main fault current limiting impedance, which is in the secondary side of a transformer in parallel with the bridge. In a soft transition mechanism, fault current is diverted from the IGBT path to the SCR path. Therefore, the fault current is limited by the impedance controlled via the SCRs.

Overcurrent Protection in AC Power Systems
Overload overcurrent is self-defining: Any current in excess of rated-load current is, in effect, an overload. An overload occurs when an electrical circuit, whether by the original design of a new circuit or by modification of an existing circuit, is required to convey load current in excess of the rated-load ampacity of the circuit conductors.
