    of tests. There. are 4 different types of LLT’s: Earth Leakage test, Enclosure Leakage test, Patient Leakage. Current test, and Patient Auxiliary Current test (we will discuss each type of test later in the. document). Each test is performed under nominal operating conditions as well as in a variety

    that incorporates an Isolation Transformer which is the preferred method. The current leakage path to earth ground has been eliminated with the use of the isolation transformer. This effectively eliminates the shock hazard. ��. Instruments for Electrical. Safety Testing . . . Since 1936. Use of an Isolation

    mA. Table I. Leakage currents —maximum allowable for each equipment classification type. From the table it is clear that the maximum earth leakage current that a switch-mode power supply can have is 300 uA. However, it is better to design the unit to have a maximum earth leakage current of 100

    , some sections are routinely applied in the production line environment. One of the most important and critical tests specified in IEC 601-1 is conducted with a circuit similar to that shown in Figure 3. It measures earth leakage current, which is essentially a sum of all leakages in the product under

    , there are plenty of opportunities for increasing productivity. Six tests are commonly performed at a production level: Figure 3. Earth leakage current test. This test is conducted under the following conditions: normal (S1 to the right, S2 closed), reversed line (S1 to the left, S2 closed), single-fault
  • Medical Device Link .
    , the new IEC standard has redefined earth leakage current as the currents flowing inside of the equipment (and therefore not hazardous to users or patients) and the mains distribution system. For this reason, earth leakage currents are limited (by the IEC standard) only such that they do not damage
