WebLeakage current is the current that streams from either DC or AC circuit in an equipment to the ground or framework and can be from the output or input. If the equipment is not properly grounded, the current flows through other paths such as the human body. This mighty also occur if the ground is incompetent or is disrupted unintentionally or ... WebThis tester consists of a DC ammeter and a few other components. The test measures the resistance at the micro- or milli-ohm level and is used primarily to verify that electrical connections are made properly, and can detect the following problems: Loose connections Adequate tension on bolted joints Eroded contact surfaces Webearth (e.g. via the enclosure of ME equipment), are negligible. 1 A procedure whereby an electrical conductor is placed within the heart of a patient or is likely to come into contact … hid smart readers
