Instruction Manual
following the instruction of the approved
set of drawing. This changing ratio is
made by means of reconnection bars
located in the headhousing, closer to
primary terminals. Please refer to the set
of
drawing
reconnection bars need to be positioned
in order to have the required ratio.
6.4. Secondary terminals/Neutral
Terminal
The unit is shipped with the current
transformer secondary short circuited
and connected to the secondary box
ground, the voltage transformer part is
open circuited and not grounded.
Attention!
Do not leave any secondary windings
of the current transformer part open
- High Voltage!
Do not short-circuit the secondary
winding of the voltage transformer
part! The neutral terminal of the
voltage transformer part must be
connected to ground prior to and
during operation!
6.5. Terminal marking
Primary and secondary terminal marking
are done according to the specified
standard. please refer to the set of
drawing.

7. OIL LEVEL INDICATOR
the
The position of the oil indicator can be
verified through the rectangular window
of the top cover.
The plate of the indicator is divided in
three areas. Central area shows the
green strip and higher and lower areas
are shown with a red strip. In normal
conditions, the indicator shows the
green strip of the indicator.
In case of oil level indicator is in either of
the red areas, the transformer must be
removed
informed immediately.
8. INSPECTION BEFORE FIRST
ENERGIZING
After putting the CITs in vertical
position, it is necessary to wait at
least 48 hours before energizing it!
Verify terminals connections to
assure the correct tightening torque.
Make sure that the neutral terminal
of the voltage transformer part (H2,
N ...) is connected to ground. Confirm
all intended groundings.
