Connecting Transformer to Earth Ground Tester
W Caution
Corrosion and paint on a pylon can impede the connection
between the contact clamp and the pylon’s frame. When
installing the contact clamp, ensure the tip of the clamp
fastener penetrates all layers of paint and corrosion.
1. Install the contact clamp to the pylon and tighten the clamp fastener.
The contact clamp can now be used as the connection point for the
Tester’s earth ground electrode test lead. See Figure 4.
2. Install a test lead from the Tester’s earth ground electrode jack to the
contact clamp. Plug the test lead into the bore hole in the clamp and
tighten the tightening screw. See Figure 4.
For Fluke 1625 / 1623 GEO Earth/Ground Testers, the earth ground
electrode jack is labeled C1 or E.
3. Install the 12-m (40-ft) test leads from the Tester’s Ajack to the
Transformer’s transformation ratio connections. To determine which
transformation ratio connections to use, see “Determining
Transformation Ratio Connections.”
4. In accordance with the Tester’s users manual, install test leads from
Tester to the probe and auxiliary earth electrode, and then perform
your earth ground resistance measurement (R
E).
