  2. VLF cable testing - Wikipedia

    en.wikipedia.org/wiki/VLF_cable_testing

    VLF cable testing (Very Low Frequency) is a technique for testing of medium and high voltage (MV and HV) cables. VLF systems are advantageous in that they can be manufactured to be small and lightweight; making them useful – especially for field testing where transport and space can be issues.

  3. Cable fault location - Wikipedia

    en.wikipedia.org/wiki/Cable_fault_location

    The conventionally used aid in cable fault testing and location is the cable test van. The van is installed with conventional cable measuring systems for quickly reaching the location of any cable fault. In 20 years that followed, over 2000 fault location vehicles were manufactured, more than half of which were intended for the former USSR.

  4. Time-domain reflectometer - Wikipedia

    en.wikipedia.org/wiki/Time-domain_reflectometer

    The Dam Safety Interest Group of CEA Technologies, Inc. (CEATI), a consortium of electrical power organizations, has applied Spread-spectrum time-domain reflectometry to identify potential faults in concrete dam anchor cables. The key benefit of Time Domain reflectometry over other testing methods is the non-destructive method of these tests. [10]

    IEC 62153 Metallic communication cables test methods; IEC 62155 Hollow pressurized and unpressurized ceramic and glass insulators for use in electrical equipment with rated voltages greater than 1 000 V; IEC 62156 Digital video recording with video compression 12,65 mm type D-9 component format 525/60 and 625/50 (Digital S)

  6. Cable tester - Wikipedia

    en.wikipedia.org/wiki/Cable_tester

    A cable tester is an electronic device used to verify the electrical connections in a signal cable or other wired assembly. Basic cable testers are continuity testers that verify the existence of a conductive path between ends of the cable, and verify the correct wiring of connectors on the cable. More advanced cable testers can measure the ...

  7. Eddy-current testing - Wikipedia

    en.wikipedia.org/wiki/Eddy-current_testing

    Variations in the electrical conductivity and magnetic permeability of the test object, and the presence of defects causes a change in eddy current and a corresponding change in phase and amplitude that can be detected by measuring the impedance changes in the coil, which is a telltale sign of the presence of defects. [5]

  8. Electrical safety testing - Wikipedia

    en.wikipedia.org/wiki/Electrical_safety_testing

    An insulation resistance test (IR test) measures the electrical resistance of insulation by applying a voltage between two locations, and measuring the resultant current flow. Proper safety precautions must be taken when doing this test, such as exclusion zones, making sure no wires are exposed, and personal protective equipment is worn.

  9. High-voltage cable - Wikipedia

    en.wikipedia.org/wiki/High-voltage_cable

    Hence, there are various test and measurement methods to prove fully functional cables or to detect faulty ones. While paper cables are primarily tested with DC insulation resistance tests the most common test for solid dielectric cable systems is the partial discharge test. One needs to distinguish between cable testing and cable diagnosis ...
