Probe resistance and auxiliary earth resistance are also measured and displayed. Before measuring, the instruments identify existing interference and select a measurement frequency to minimise its effect. All measured data, as well as the time-of-day the measurement was taken, can be sent to computer or printed via an RSC interface. 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!

In many cases, these safety measures are national and international regulations which must be checked regularly.

Other insulation meters in this category can, at best, provide an instrument with analog display whose size and weight do not meet the wishes of the users.


Finally, the device must provide all of this information reliably with the greatest possible simplicity and ease of use. All safety controls are always based on insulation resistance measurements. Overvoltage suppressors or other voltage limiting elements also have to be tested for faultless functioning. Despite all these requirements simple operation, high overload capacity and protection against misoperation of the instrument must be guaranteed. The instrument meets highest technical requirements while covering as broad an area of application as possible and complies with all relevant regulations governing construction, safety and measurement.

New regulations and increasing nominal mains voltages make ever greater demands on the measuring engineer and his test instruments. Large fields of applications, the seasonal variations of the earth resistance, variations from weather and ground conditions, require test llem able to collect and isl additional information in order to ensure that the conditions under which the measurement was taken are known and that the results are reproducible.

This has resulted an increasing number of areas of application for V insulation meters. 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.


The construction and operation of electrical devices and installations require the compliance with certain safety precautions to protect man. It’s a community-based project which helps to repair anything.

Selective measurement of individual earth electrode resistance in interlinked or parallel ground systems i. These safety controls are laid down in national and international regulations and must be checked at regular intervals. AFC switch positon measuring range RA 2pole 0. The insulation quality of materials and various objects also has to be tested for instance. One specific application of this capability is quick and accurate measurement of power pylon grounds.

Selective measurement at high voltage pylons: AFC switchable switch position measuring range resolution RA 2-pole 0. 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.

The requirements in practice vary a great deal, however. The insulation measurement which, as such, is basically simple faces multiple types of applications.
