Earth Tester
TAURUS PRECIOHM ET
-
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.

Ground-Fault Products for Solidly Grounded Systems
-
Ground-fault products are used to monitor grounded systems (ungrounded and grounded) for fault currents or residual currents. The sum of all conductors except the protective earth conductor is measured by means of measuring current transformers.In general, ground-fault monitors (RCM - residual current monitors) are used to send a message to the user even before reaching the shutdown threshold of the GFCI. Ground-fault monitors detect deteriorations of the insulation level at an early stage and in a reliable way.

Battery boxes can be tested for faults by placing the box on a metal plate. By applying a test voltage to an electrode inside the box, the moulding can be checked thoroughly - particularly at the injection points - and any faults found. Defects will be identified by a spark passing from the electrode, through the defect itself, to earth (the conductive material placed outside the battery box.
