Figure 80: VT Winding Results
Winding resistance test is used to determine if the dc resistance of theVT secondary winding is within
specification or not. A DC current is applied and voltage is measured to determine the winding
resistance for the selected winding. After measurement the winding resistance is calculated displayed in
on the screen.
11.0 Self Test
Refer to the safety instructions first before use of the equipment.
1. Verify the Power ON/OFF switch is OFF. Power the test set from a suitable source
of power (95-125 or 195-265 V50/60 Hz).
2. Connect the ground wing nut to a suitable ground.
WARNING
There is always the possibility of voltages being induced at the terminals of a test specimen
because of proximity to high voltage energized lines. A residual static voltage charge may also
be present at these terminals. Ground each terminal to be tested with a safety ground stick,
before making connections.
WARNING
The MRCT produces high voltages and currents during the performance of tests. DO NOT
TOUCH connector clips or test leads while the MRCT is performing a test.
