Leakage Test (To protect electric shock when customer touch the terminal.) Leakage current can be measured by V: Voltmeter or oscilloscope (r.m.s. or peak reading) Stabilized power supply instrument and isolated voltage transformer: Use too much current capacity and isolated voltage transformer does not need to use stabilized power supply equipment. Specification of RMS volt meter: Input resistance > 1 Mohm, Input capacitance < 200 pF, Frequency range: 15 Hz – 1MHz . Refer Figure 2. Isolated type volt - meter (FLUKE 8921A etc *1) *1 Not use FLUKE 8920A that connected to protective earth by diode # Leakage current of measurement instrument is less than 10μArms when under test equipment AC plug is opened # Set up the following condition and turn on the set. Applied voltage: Nominal input voltage (Description on Nameplate) # Measure the leakage current between one phase conductor and neutral for terminal A and terminal B.
