3. Move Function Knob to 100uA/Div position.
4.
Press and hold “Test” button. Ramp test voltage to desired Megohm
test voltage and press the “Time=0” button at the top of the screen after
reaching required voltage.
5. Adjust “uA/div” knob if required to get the machine in the most
accurate current range for observed leakage current. The DR Series
tester will place a message on the screen if it should be moved to a
lower current range.
6. After time has elapsed for the Megohm test, usually 60 seconds per
IEEE 43, press the “Save Hipot” button. The Megohm data will be
displayed in the middle of the screen between the voltage and current
slider bars. Data acquired at 30 seconds and at 1 minute will be
displayed. These two values are required for calculation of the DA and
PI tests. The tester automatically acquires these values; however, if
only a Megohm test is required, these data points will not be used.
Performing Only DC Over Voltage
Test (DC HiPot Test)
1. Connect appropriate high voltage leads
to stator windings.
2.
Move Test Lead selector switch
to “HiPot” position.
3.
Move Function Knob to 100uA/Div position
4.
Press and hold “Test” button. Ramp test voltage to desired Megohm
test voltage and press the “Time=0” button at the top of the screen after
reaching required voltage.
5. Adjust “uA/div” knob if required to get machine in the most accurate
current range for reading leakage current. The DR Series tester will
place a message on the screen if it should be moved to a lower current
range.
