Assembled Radial Spacer with Probe
6.
Use a wood clamp to compress the laminated spacer for approximately 15 minutes to allow the glue to
dry.
To install the probe into coil assembly with spacer:
1.
Insert the modified spacer into the winding after sizing, just before installing the winding onto its core.
2.
Create a separation in the winding with wedges.
3.
Insert the modified spacer.
4.
Remove the wedges.

Installing Probe Tip in a Shell Form Transformer
If probes will be installed in the shell form transformer, use the following installation procedure. Tape the probe
tip directly onto the winding conductor in the hottest region of the winding (determined by the transformer
manufacturer).
To place the sensor:
1.
Position the sensor against a portion of the conductor so that it cannot be crushed by an adjacent winding
turn if a sudden change in current through the windings produces abrupt contraction of the coils.
2.
For best response, tape the sensor “side-on” (the side of the probe is directly against the winding surface).
The figure below illustrates a possible probe-tip mount.
