  2. Electrical safety testing - Wikipedia

    en.wikipedia.org/wiki/Electrical_safety_testing

    A survey without touching anything, and looking at the electrical installation or product before starting any electrical testing. A visual inspection seeks to identify damaged insulation, disconnected wires, incorrect installation, and any other visual issues. Dead testing. Continuity test: a test to check the wiring is correct

  3. In-circuit testing - Wikipedia

    en.wikipedia.org/wiki/In-circuit_testing

    A common form of in-circuit testing uses a bed-of-nails tester.This is a fixture that uses an array of spring-loaded pins known as "pogo pins". When a printed circuit board is aligned with and pressed down onto the bed-of-nails tester, the pins make electrical contact with locations on the circuit board, allowing them to be used as test points for in-circuit testing.

  4. On-board diagnostics - Wikipedia

    en.wikipedia.org/wiki/On-board_diagnostics

    On-board diagnostics (OBD) is a term referring to a vehicle's self-diagnostic and reporting capability. In the United States, this capability is a requirement to comply with federal emissions standards to detect failures that may increase the vehicle tailpipe emissions to more than 150% of the standard to which it was originally certified.

  5. Electrical isolation test - Wikipedia

    en.wikipedia.org/wiki/Electrical_isolation_test

    In electrical engineering, an electrical isolation test is a direct current (DC) or alternating current (AC) resistance test that is performed on sub-systems of an electronic system to verify that a specified level of isolation resistance is met. Isolation testing may also be conducted between one or more electrical circuits of the same ...

  6. Fault detection and isolation - Wikipedia

    en.wikipedia.org/wiki/Fault_detection_and_isolation

    For example, if a fault is detected in hydraulic system 1, then the truth table sends an event to the state chart that the left inner actuator should be turned off. One of the benefits of this model-based FDI technique is that this reactive controller can also be connected to a continuous-time model of the actuator hydraulics, allowing the ...

    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.
