TAURUS PRECIOHM ET -
Taurus Powertronics Systems
The TAURUS PRECIOHM ET is one of the specially designed products by TAURUS to measure earth resistivity and earth resistance in a power station. These tests are performed based on 4 point (Wenner) and 3 point (fall of potential) methods respectively. All electrical equipment in the substation and power stations are electrically connected to station earth mat with earth electrodes. The earth electrode ensures that in the event over voltage on the system due to system fault or lighting discharges etc., the parts of the equipment which are normally ”dead” as far as voltages are concerned; do not attain dangerously high potentials. An earth electrode will only be effective so long it has a low resistance to the earth and can carry large currents without deteriorating. Thus the resistance of earth electrode should be low to give good protection and it must be continuously measured and monitored in all the substations and power stations.

Kyoritsu Electrical Instruments Works, Ltd.
Earth Ground Testing. Most facilities have grounded electrical systems, so that in the event of a lightning strike or utility overvoltage, current will find a safe path to earth. A ground electrode provides the contact between the electrical system and the earth.

EM-4055 -
MEGABRAS srl
The EM-4055 Earth Meter is a digital, microprocessor-controlled instrument that allows to measure the earth resistance and ground resistivity (using Wenner´s method), as well as to detect parasitic voltages present in the ground. This instrument is well suitable to measure earth systems in power substations, industries, distribution networks, etc., according to VDE 0413. It is also suitable for soil resistivity measurements, in order to optimize the earth systems project

EM2 -
Alpha Lab, Inc.
The Earth Magnetometer Model EM2 measures small variations from location to location in the Earth magnetic field associated with buried magnetic masses. Unlike metal detectors, a magnetometer signal is not attenuated by rock, dirt, mud or water, so targets can be detected at great depth. (If D is the diameter of a mass of magnetizable material, the EM2 can detect it as deep as 40 times the diameter D, whether the mass is specifically magnetized or not.) It is the lightest weight and lowest cost magnetometer available which can reliably measure differences down to 1 nT from point to point.

The Motwane Manufacturing Company
Earth resistance testing measures earth electrode resistance and soil resistivity. A good, low resistance ground connection prevents injuries due to faulty installation and protects sensitive equipment against electromagnetic interference. Motwane’s range of earth resistance products offers a fall-of-potential and clamp-on method for testing earth resistance and soil resistivity.
