  2. Electrical isolation test - Wikipedia

    en.wikipedia.org/wiki/Electrical_isolation_test

    The test often reveals problems that occurred during assembly, such as defective components, improper component placement, and insulator defects that may cause inadvertent shorting or grounding to chassis, in turn, compromising electrical circuit quality and product safety. [2]

  3. Floating ground - Wikipedia

    en.wikipedia.org/wiki/Floating_ground

    Floating grounds can be dangerous if they are caused by failure to properly ground equipment that was designed to require grounding because the chassis can be at a very different potential from that of any nearby organisms, who then get an electric shock upon touching it. Live chassis TVs, also known as hot chassis, where the set's ground is ...

  4. Chassis ground - Wikipedia

    en.wikipedia.org/wiki/Chassis_ground

    A chassis ground is a link between different metallic parts of a machine to ensure an electrical connection between them. [1] Examples include electronic instruments and motor vehicles. Usages

  5. Bent pin analysis - Wikipedia

    en.wikipedia.org/wiki/Bent_Pin_Analysis

    In some very commonly used miniature D connectors, it is possible that a bent pin can touch two neighboring contacts plus a grounded connector shell, thus shorting chassis ground to three electrical paths. The connector in Figure 3 is an example: its mating plug connector (not shown) fits inside the Figure 3 receptacle shell, and the plug's ...

  6. Ground (electricity) - Wikipedia

    en.wikipedia.org/wiki/Ground_(electricity)

    The use of the term ground (or earth) is so common in electrical and electronics applications that circuits in portable electronic devices, such as cell phones and media players, as well as circuits in vehicles, may be spoken of as having a "ground" or chassis ground connection without any actual connection to the Earth, despite "common" being ...

  7. 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. Appliance classes - Wikipedia

    en.wikipedia.org/wiki/Appliance_classes

    These appliances do not have their chassis connected to electrical earth. In many countries the plug of a class 0 equipment is such that it cannot be inserted to grounded outlet like Schuko . The failure of such an equipment in a location where there are grounded equipment can cause fatal shock if one touches both.
