Megger 1014430 OffersPinpointing means precisely locating faults in the cable sheath. These faults cause the measuring current to flow into the ground. When the measuring current exits the cable at the fault point, the current builds a voltage gradient which can be measured by earth rods and earth fault locators. The step voltage method accurately locates sheath faults: as it approaches the fault point, the step voltage potential increases. After it passes the fault, the potential decreases with reversed polarity. The change in polarity allows the fault to be located precisely.
The ESG NT2 earth fault locator measures the step voltage potential produced by underground test generators. Other existing underground distortions such as potential equalisation current, DC offset, 16 ²/³ Hz or influences from cathodic protection systems are automatically detected and eliminated. The automatic zero calibration maintains the display calibration continuously at zero.
The ESG NT2 has a high-contrast color display on which the measured step voltage is displayed in two ways: as a bar graph (similar to a conventional pointer instrument), and as a continuous “history-display” which shows both the current process and the last 5 to 6 measurement records. In this way, changes are displayed clearly and continuously.
