At the locations involving the generation, distribution and consumption
of electrical energy, certain safety measures must be met in order to
protect human life. In many cases, these safety measures are national
and international regulations which must be checked regularly. Earthing,
the connection of exposed conductive parts to the earth in case of a
fault, represents the most fundamental safety measure. Real life
requires the earthing of transformers, high and medium voltage power
pylons, railway tracks, tanks, vats, foundations and lightning
protection systems. Large fields of applications, the seasonal
variations of the earth resistance, variations from weather and ground
conditions, require test instrument able to collect and document
additional information in order to ensure that the conditions under
which the measurement was taken are known and that the results are
reproducible. Finally, the device must provide all of this information
reliably with the greatest possible simplicity and ease of use. The
SATURN GEO and SATURN GEO X provide 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 minimize interference. Before measuring, the instruments identify
existing interference and select a measurement frequency to minimize 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. All measured
data, as well as the time-of-day the measurement was taken, can be sent
to computer or printed via an RS-232C interface. |
