Description
|
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 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. 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.
