PM-19-10-004, Rev F
Notes:
1.
Terminal G is internally connected to the KATC-V front panel and
chassis
— and grounded through the power cord plug.
2.
If the power cord is ungrounded, connect G to system ground.
3.
If the power cord is grounded, and one of the secondary leads is at
system ground,
do not
connect G to system ground.
4.
If the power cord is grounded, and it is desired to ground the trans-
former secondary, this may be accomplished by connecting G to S,
U, or C, as appropriate.
One-to-One Test
The One-to-One test is a method for checking the calibration of the KATC-V
and associated standard transformer. The One-to-One test shown in Figure
2 is to be used if you are not using the KATC-V with the Knopp KVTS or
1G2 Transformer Test System. If the KATC-V is installed in a KVTS or 1G2,
see the instruction manual included with that unit for information on running
the One-to-One test.
