Page 9: Introduction
EI-162BN Split-Core Transformer Introduction The Fluke EI-162BN Split-Core Transformer (hereafter referred to as the “Transformer”) is used with an earth ground tester (hereafter referred to as the “Tester”) to make selective earth ground resistance measurements (R ) on transmission line pylons. The Transformer is designed to work with Fluke 1625 and 1623 GEO Earth Ground Testers. -
Page 10: Safety Regulations
EI-162BN Users Manual Safety Regulations This device is only to be installed and operated by qualified personnel in compliance with the safety precautions and regulations that follow. Additionally, use of this device requires compliance with all legal and safety regulations pertaining to each specific application. Similar regulations apply to the use of accessories. -

EI-162BN Users Manual 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. - Page 15 Split-Core Transformer Using the Split-Core Transformer evx02.eps Figure 2.

Page 16: Determining Transformation Ratio Connections
EI-162BN Users Manual 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 (⊥). - Page 17 Split-Core Transformer Using the Split-Core Transformer 1 : 200 1 : 300 1 : 500 1 : 800 1 : 1000 evx03.eps Figure 3.

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. - Page 19 Split-Core Transformer Using the Split-Core Transformer Parasitic Current Aux.
