•
The DVAR current on Transformer 1 is lagging
•
The DVAR current on Transformer 2 is leading
•
The DVAR current on Transformers 1 and 2 have the same magnitude
•
The DVAR current on Transformer 3 should be at or near zero
63. Manually place the transformers to the same tap position (or the same difference as
noted above).
64. Close the Low Side Breaker for Transformer 3 and verify that the DVAR current in
all the transformers is at or near zero.
Assuming all the transformers are the same and the high side sources are all
connected together, only one high side source for the paralleled transformers. If the
high side is not connected together then it may be necessary to adjust the tap
positions to achieve zero DVAR current or the minimum value possible.
—Test complete.—
Place the desired settings on the controls and set all controls to Automatic.
