We are well known Exporter, Manufacturer & Supplier of Earth Tester in Bengaluru, Karnataka, India. The Preciohm ET is one of the specially designed product 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.
