Electrical Safety

The SebaKMT ESG NT earth fault locator is used for the high accuracy pinpointing of a sheath fault. The SebaKMT ESG NT has state of the art technology in connection with a bright, sun readable TFT colour display which allows a very easy use.

The ESG NT digital earth fault locator displays the measured step voltage in two ways: as a bar graph (similar to a conventional pointer instrument) and as a continuing 'history display' which shows both the current process and the last 5 to 6 measurement records. A fully automatic calibration on the SebaKMT ESG NT earth fault locator keeps the display always at zero and the integrated noise suppression eliminates all influences by DC, Railway currents, industrial plants and high resistive soil environment. 

The SebaKMT ESG NT earth fault locator measures the step voltage potential produced by a test generator in the underground. The ESG NT automatically detects and eliminates other existing underground distortions, such as potential equalisation current, DC offset, 16 2/3 Hz or influences of cathodic protection systems. 

The SebaKMT ESG NT adapts automatically to the input voltage level and has an automatic pulse detection which allows working with almost any type of pulse generator. 

SebaKMT ESG NT Digital Earth Fault Locator Key Benefits:

Automatic adaptation to voltage level

Automatic zero calibration, no adjustments necessary
SebaKMT ESG NT has a history mode
High-contrast colour display

The SebaKMT Pinpointing Procedure: Pinpointing means the precise location of faults in the cable sheath. These faults cause the measuring current to flow into the ground. When it exits the cable at the fault point, the measuring current builds a voltage gradient which can be measured by earth rods and earth fault locators. The accurate location of sheath faults is done by the step voltage method: as it approaches the fault point, the step voltage potential increases, decreasing with reversed polarity after it passes the fault. The change in polarity allows the fault to be located precisely.
