Ground or earth faults are the common cause of fire and electrical shock on personnel. The effectiveness of a ground connection can be affected by environmental factors like the weather. Regular testing ensures that everything is in good condition and functioning within the normal limits.
Electrical grounds should meet a specific resistance range to be considered within normal limits. Depending on the application, the normal ground resistance is usually 25 ohms or lower.
The Megger DET4TD Earth Tester is a high performance ground tester which features two, three and four point ground testing. It has a selectable 25 volts and 50 volts voltage output.
It is capable of measuring resistances from 0.01 Ohms to 20 Kilo Ohms and earth voltages of up to 100 volts.
