2. Analog delay line - Wikipedia

   en.wikipedia.org/wiki/Analog_delay_line

   One example of an analog delay line is a bucket-brigade device. [1] Other types of delay line include acoustic (usually ultrasonic), magnetostrictive, and surface acoustic wave devices. A series of resistor–capacitor circuits (RC circuits) can be cascaded to form a delay. A long transmission line can also provide a delay element. The delay ...

3. Circuit breaker (overcurrent) - Wikipedia

   en.wikipedia.org/wiki/B32_circuit_breaker

   Ambient temperature affects the time delay but does not affect the current rating of a magnetic breaker. [12] A large power circuit breaker, such as one applied in circuits of more than 1000 volts, may incorporate hydraulic elements in the contact operating mechanism. Hydraulic energy may be supplied by a pump or stored in accumulators.

4. Distribution board - Wikipedia

   en.wikipedia.org/wiki/Distribution_board

   A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.

5. Bucket-brigade device - Wikipedia

   en.wikipedia.org/wiki/Bucket-brigade_device

   The SAD-512 was a single delay line version. The Philips Semiconductors TDA1022 [ 3 ] similarly offered a 512-stage delay line but with a clock rate range of 5–500 kHz. Other common BBD chips include the Panasonic MN3002, MN3005, [ 4 ] MN3007, [ 5 ] MN3204 and MN3205, [ 6 ] with the primary differences being the available delay time.

6. Residual-current device - Wikipedia

   en.wikipedia.org/wiki/Residual-current_device

   A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...

7. Power system protection - Wikipedia

   en.wikipedia.org/wiki/Power_system_protection

   Circuit breakers or RCDs to open/close the system based on relay and autorecloser commands; Batteries to provide power in case of power disconnection in the system; Communication channels to allow analysis of current and voltage at remote terminals of a line and to allow remote tripping of equipment.
