Megeer ESG NT Digital earth fault locator

The Megger ESG NT Ground Fault Locator is an advanced tool designed to pinpoint cable sheath faults with exceptional accuracy. Its standout feature is a bright, sunlight-readable TFT color display, ensuring ease of use even in challenging field conditions. The display provides results in two formats: a bar graph, which mimics an analog display, and a history display that shows the deflections of the last seven pulses, giving users a comprehensive view of fault data over time.

The ESG NT boasts a fully automatic calibration system that keeps the display consistently at zero, ensuring accurate readings without manual adjustments. Additionally, its integrated noise suppression technology eliminates the impact of external influences such as DC currents, railway currents, industrial plants, and high-resistive soil environments. This feature enhances the reliability and precision of fault location.

By utilizing two earth rods, the ESG NT measures the ground step voltage potential, and the direction towards the fault is indicated on the display. This method provides clear and direct guidance to the fault location, streamlining the troubleshooting process.

Ideal for field use, the Megger ESG NT combines robust functionality with user-friendly features. The sunlight-readable display and clear bar graph results make it an invaluable tool for technicians working in various environmental conditions. The history mode further aids in fault analysis by allowing users to review the deviation of the last seven pulses, offering a deeper insight into the fault characteristics.
