2. Transient recovery voltage - Wikipedia

   en.wikipedia.org/wiki/Transient_Recovery_Voltage

   Examples of TRV waveshapes. A transient recovery voltage (TRV) for high-voltage circuit breakers is the voltage that appears across the terminals after current interruption. It is a critical parameter for fault interruption by a high-voltage circuit breaker, its characteristics (amplitude, rate of rise) can lead either to a successful current interruption or to a failure (called reignition or ...

3. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   All circuit breaker systems have common features in their operation, but details vary substantially depending on the voltage class, current rating and type of the circuit breaker. The circuit breaker must first detect a fault condition. In small mains and low-voltage circuit breakers, this is usually done within the device itself. Typically ...

4. Arc-fault circuit interrupter - Wikipedia

   en.wikipedia.org/wiki/Arc-fault_circuit_interrupter

   An arc-fault circuit interrupter (AFCI) or arc-fault detection device (AFDD) [1] is a circuit breaker that breaks the circuit when it detects the electric arcs that are a signature of loose connections in home wiring. Loose connections, which can develop over time, can sometimes become hot enough to ignite house fires.

5. Recloser - Wikipedia

   en.wikipedia.org/wiki/Recloser

   Each sectionalizer detects and counts fault current interruptions by the recloser (or circuit breaker). After a pre-determined number of interruptions, the sectionalizer will open, thereby isolating the faulty section of the circuit, allowing the recloser to restore supply to the other non-fault sections. [18]

6. Electrical fault - Wikipedia

   en.wikipedia.org/wiki/Electrical_fault

   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.

7. Power system protection - Wikipedia

   en.wikipedia.org/wiki/Power_system_protection

   Distance protection detects both voltage and current. A fault on a circuit will generally create a sag in the voltage level. If the ratio of voltage to current measured at the relay terminals, which equates to an impedance, lands within a predetermined level the circuit breaker will operate.

8. Arc fault - Wikipedia

   en.wikipedia.org/wiki/Arc_fault

   Two types of wiring protection are standard thermal breakers and arc fault circuit breakers. Thermal breakers require an overload condition long enough that a heating element in the breaker trips the breaker off. In contrast, arc fault circuit breakers use magnetic or other means to detect increases in current draw much more quickly.

9. Circuit breaker design pattern - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker_design_pattern

   The Circuit Breaker is a design pattern commonly used in software development to improve system resilience and fault tolerance. Circuit breaker pattern can prevent cascading failures particularly in distributed systems. [1] In distributed systems, the Circuit Breaker pattern can be used to monitor service health and can detect failures dynamically.
