A fault current limiter (FCL), also known as fault current controller (FCC), [1] is a device which limits the prospective fault current when a fault occurs (e.g. in a power transmission network) without complete disconnection. The term includes superconducting, solid-state and inductive devices. [2]
An inrush current limiter is a device or devices combination used to limit inrush current. Passive resistive components such as resistors (with power dissipation drawback), or negative temperature coefficient (NTC) thermistors are simple options while the positive one (PTC) is used to limit max current afterward as the circuit has been operating (with cool-down time drawback on both).
A little confusion further is that (S)FCLs own their own controller inside. Doc #1 states: "Because the fault current is controlled dynamically through the power electronics, the SSFCL is sometimes referred to as a fault-current controller (FCC)". Other links for illustrating the confusion: , , , , . There is no indication however that the link ...
The coming week could see demand topple the current record for May of 71,645 MW set in 2022, while still trailing the all-time high of 85,508 MW set on Aug. 10, 2023. ... Texas power prices surged ...
The Texas House and Senate have advanced proposals that would spend $1.5 billion to complete 100 miles of barriers along some of the high-traffic areas of the 1,254-mile Texas-Mexico border.
Earth fault protection also requires current transformers and senses an imbalance in a three-phase circuit. Normally the three phase currents are in balance, i.e. roughly equal in magnitude. If one or two phases become connected to earth via a low impedance path, their magnitudes will increase dramatically, as will current imbalance.

Current limiting reactors, once called current limiting reactance coils, were first presented in 1915. [2] The inventor of the current limiting reactance coil was Vern E. Alden who filed the patent on November 20, 1917 with an issue date of September 11, 1923. The original assignee was Westinghouse Electric & Manufacturing Company. [3]
