LEM GEO X STAKELESS TESTER
Weekly Hire Cost From: £85.00
The SATURN GEO X provides the perfect solution by combining the latest technology and years of LEM experience into a compact, field-rugged and extremely easy to use instrument. In addition to performing standard 3- and 4-pole earth resistance measurements, an innovative process accurately measures individual earth electrode resistances in single and meshed earthed systems without disconnecting any parallel electrodes! One specific application of this capability is quick and accurate measurement of power pylon grounds.
The SATURN GEO (X) also incorporates the first truly automatic frequency control (AFC) to minimise interference. Before measuring, the instruments identify existing interference and select a measurement frequency to minimise its effect. The SATURN GEO (X) incorporates microprocessor controlled automatic measurements including checking probe hookup to ensure measurements are taken correctly and measuring all probe ground resistances to ensure reliable, repeatable results. Probe resistance and auxiliary earth resistance are also measured and displayed.
Earthing resistance 3-pole and 4-pole of 0.001?...300k?, with voltages of 20 V/48 V AC, with frequencies of 94, 105, 111, 128 Hz or AFC (Automatic Frequency Control), with automatic test of test lead connection and adjustable limit values Resistance 2-pole AC 0.001?...300 k? Noise voltage up to 50 V, noise frequency.
Measurement of the earthing impedance of electricity pylons Selective measurement of individual earth electrode resistance in interlinked or parallel ground systems (i.e. power pylons, grounding grids, lightning protection systems) without influence from other grounds. Low resistance 2- and 4-pole 0.001 ?...3 k? with automatic polarity reversing and high short-circuit current as per IEC 61557-4 Stakeless earth testing is carried out using the clamp method.
