Page 9: Introduction Introduction The Earth Ground Tester Tester or Product is a compact, field-rugged instrument that performs all four types of earth ground measurement. Specifically, the Tester is able to measure earth ground loop resistances using only clamps — called Stakeless testing. Page Safety Information Users Manual Safety Information A Warning identifies hazardous conditions and procedures that are dangerous to the user. A Caution identifies conditions and procedures that can cause damage to the Product or the equipment under test.

Do not dispose of this product as unsorted municipal waste. Storage If the Tester is stored for an extended period of time or is not in use for a long time, you The transformer has a transformation ratio between 80 and for the measurement of a single branch in mesh-operated earthing systems.

This enables the user to measure on high voltage pylons without separating the overhead earth wires or earth strips at the bottom of the pylons. Table 3. See Table 4 for location and description of each display element. Table 4. Display edv If you have problems, see How to Troubleshoot.

Battery Insertion Measurement values are shown on a liquid crystal display with correct decimal point and unit. Additional special characters indicate measurement mode, operating condition, and error messages. The Tester also makes measurements with an external current transformer, with which a measurement of single resistance branches in interlinked networks lightning protection and high voltage pylons with cabling can be performed without separating parts of the system.

R 3-Pole Measurement See Figure 5. Connect test leads. R 4-Pole Measurements See Figure 6. See Figure 7. Earth ground stakes are not used. A known voltage is induced by one clamp, and the current is measured with the second clamp. Stakeless Ground Loop Measurement Page Advanced Operation - allows measurements of earth electrode resistances without disconnection of the earthing system or disengaging the overhead earth wire.

See Figure 9. Page 30 Users Manual As all four pylon stubs are connected to the foundation earth of the pylon, the measuring current I is divided into five components according to the present resistances meas involved. One part flows via pylon construction to the overhead earth wire and further to the parallel circuited pylon earthing resistances. Read out measured value R Note Before setting the earth stakes for probe and auxiliary earth electrode make sure that the probe is set outside the potential gradient of earth electrode and auxiliary earth electrode.

Wenner, A method of measuring earth resistivity; Bull. Measurement of Soil Resistivity 1. See Figure 11 for steps Table 6. Troubleshooting Step Description External voltage Uext too high If the external voltage applied to the instrument is too high, usually from leakage currents in the system under test, no measurement can be started see Specifications for Uext limit.
