6.8 Demagnetization
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.
3 On test lead set labeled CT X/S connect the high voltage connector color coded green to the
MVCT high voltage connector that is color coded green and labeled SOURCE Voltage. Use the
red alignment marks on the 2 connectors to properly align them before connecting.
4 On test lead set labeled CT H/P Connect the high voltage connector color coded blue to the
MVCT high voltage connector that is color coded blue and labeled MEASUREMEMT. Use the red
alignment mark on the 2 connectors to properly align them before connecting
5 On test lead set labeled CT X/S connect the test lead binding posts X1 and X5 to secondary of
the current transformer on the desired tap. Observe the polarity marks on the CT (X1 on test
set is polarity terminal).
6 On test lead set labeled CT H/P connect the test lead primary binding posts H1 and H2 to CT
primary bushings H1 and H2.Observe the polarity marks on the CT (H1 on the test set is polarity
terminal).
7 Turn Power ON/OFF switch to ON.
8 After the boot up, in the Home Screen select the “Demagnetization” button
9 A connection diagram will appear showing how to properly connect the MVCT to the CT.
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.
