2. Electrical fault - Wikipedia

   en.wikipedia.org/wiki/Electrical_fault

   Analysis of the prospective short-circuit current is required for selection of protective devices such as fuses and circuit breakers. If a circuit is to be properly protected, the fault current must be high enough to operate the protective device within as short a time as possible; also the protective device must be able to withstand the fault ...

   Measures power in a circuit Vectorscope: Displays the phase of the colors in color TV Video signal generator: Generates video signal for testing purposes Voltmeter: Measures the potential difference between two points in a circuit. (Includes: DVM and VTVM) VU meter: Measures the level of AF signals in Volume units Cathode Ray Oscilloscope (CRO)

4. Electrical outlet tester - Wikipedia

   en.wikipedia.org/wiki/Electrical_outlet_tester

   A receptacle tester for North American wiring. An electrical outlet tester, receptacle tester, or socket tester is a small device containing a 3-prong power plug and three indicator lights, used for quickly detecting some types of incorrectly-wired electrical wall outlets or campsite supplies.

   A missing or displaced indicator thus pinpoints a blown fuse. The removable part of the fuse holder has a small window to allow inspection of the indicator without removal of the fuse. The indicator button usually has a coloured dot indicating the fuse rating (see table). D- and D0-type fuses are used for protection of circuits up to 500 V AC ...

6. Continuity tester - Wikipedia

   en.wikipedia.org/wiki/Continuity_tester

   For situations where continuity testing must be done on high resistance circuits, or where delicate conductors and sensitive components that might be damaged by excessive current are present, a low voltage, low current device must be used. [2] [4] These typically use an op-amp and watch batteries to drive an LED as an indicator. These testers ...

7. Fuse (electrical) - Wikipedia

   en.wikipedia.org/wiki/Fuse_(electrical)

   Fuses for high-voltage equipment, up to 115,000 volts, are rated by the total apparent power (megavolt-amperes, MVA) of the fault level on the circuit. Some fuses are designated high rupture capacity (HRC) or high breaking capacity (HBC) [6] and are usually filled with sand or a similar material. [7] HRC fuse with red blown indication

8. Fault indicator - Wikipedia

   en.wikipedia.org/wiki/Fault_indicator

   In electric power distribution networks, a fault indicator is a device which provides visual or remote indication of a fault on the electric power system. Also called a faulted circuit indicator (FCI), [1] the device is used in electric power distribution networks as a means of automatically detecting and identifying faults to reduce outage time.

9. Symbolic circuit analysis - Wikipedia

   en.wikipedia.org/wiki/Symbolic_Circuit_Analysis

   Symbolic circuit analysis is a formal technique of circuit analysis to calculate the behaviour or characteristic of an electric/electronic circuit with the independent variables (time or frequency), the dependent variables (voltages and currents), and (some or all of) the circuit elements represented by symbols.
