In an electric power system, a fault or fault current is any abnormal electric current. For example, a short circuit is a fault in which a live wire touches a neutral or ground wire. An open-circuit fault occurs if a circuit is interrupted by a failure of a current-carrying wire (phase or neutral) or a blown fuse or circuit breaker.
fault A short circuit, open circuit, or other disruption of a power system. fax Facsimile, the transmission of paper images by radio or by wire. feed forward A control system that adjusts the controlled variable based on a model of the process and measurements of disturbances, instead of feedback from measurement of the process. feedback amplifier
Open-circuit voltage, the difference of electrical potential between two terminals of a device when there is no external load connected; An electrical circuit is an "open circuit" if it lacks a complete path between the terminals of its power source
A sudden fail-open fault can cause multiple secondary failures if it is fast and the circuit contains an inductance; this causes large voltage spikes, which may exceed 500 volts. A broken metallisation on a chip may thus cause secondary overvoltage damage. [1]
Definition of open-circuit voltage. The box is any two-terminal device, such as a battery or solar cell. The two terminals are not connected to anything (an open circuit), so no current can flow into or out of either terminal. The voltage v oc between the terminals is the open-circuit voltage of the device.

Additionally, zones possess the following features: zones overlap, overlap regions denote circuit breakers, and all circuit breakers in a given zone with a fault will open in order to isolate the fault. Overlapped regions are created by two sets of instrument transformers and relays for each circuit breaker.
