Using the Split-Core Transformer
Installing Transformer around Pylon Footing
To install the Transformer around a pylon footing:
1. Loosen (or if required, remove) the fasteners. See Figure 2.
If extra leverage is needed to loosen a fastener, insert a lever (like a
small screwdriver) into the 4 mm bore hole in the fastener.
2. On the end face with the slotted bolt hole, pivot the fastener/bolt out
of the way, and then separate the two halves of the Transformer. See
Figure 2.
3. Install the Transformer around the pylon footing. See Figure 2.
W Caution
• Damage to the Transformer end faces can greatly impair
performance. Use care when joining the end faces
together.
• Foreign substances on the end faces can distort
measurement results. Before fastening together, ensure
the end faces are clean. If required, see “Cleaning.”
• Airgaps between the end faces can distort measurement
results. When fastening the end faces together, ensure
the fasteners are tightened firmly.
4. Join the two halves of the Transformer so the end faces meet. On the
end face with the slotted bolt hole, pivot the fastener/bolt into place.
If fasteners were removed, install the fasteners. Tighten fasteners
firmly. See Figure 2.
If extra leverage is needed to tighten a fastener, insert a lever (like a
small screwdriver) into the 4 mm bore hole in the fastener.
