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.

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.

1. 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.

Determining Transformation Ratio Connections

Before you connect the Transformer to the Tester, you need to determine a suitable transformation ratio for the minimum measuring and maximum parasitic currents expected to flow through the transmission line pylon.

The Transformer has 1000 windings, with connections at winding ratios of 1000, 500, 200 and 0 ( ). Depending on the combination of connections used, the Transformer can provide transformation ratios of 1:1000, 1:800, 1:500, 1:300, and 1:200.

See Table 2 to determine a suitable transformation ratio for the expected minimum measuring and maximum parasitic currents, and then see Figure 3 for the Transformer connections that will provide that ratio. These connections will be used for connecting the Transformer to the Tester's >c jack.

Note

Be sure to adjust your earth ground tester to the selected transformation ratio.

Table 2. Transformation Ratios

Current	Ratio
	1:1000 [1]	1:800	1:500	1:300	1:200
Min. Measuring Current [2]	0.50 mA	0.40 mA 0.25 mA	0.15 mA	0.10 mA
Max. Parasitic Current [3]	3.0 A 2.4 A	1.5 A 0.9 A	0.6 A
[1] For nearly all selective earth ground resistance measurements, a ratio of 1:1000 is recommended[2] At 94, 105, 111, and 128 Hz[3] At 50, 60 and 16-2/3 Hz
