Measurement technology/ Earth fault and short circuit indicators

Ground fault and short circuit indicator

Safely locate combined earth and short-circuit faults

Earth fault and short circuit indicator with direction-selective fault detection

Our earth fault and short circuit indicators enable reliable detection and localization of earth faults and short circuits in medium-voltage networks. The product group includes high-performance series such as the SGI fault direction indicator, the MD fault indicator, the EK series, and the NG series. Highlights include direction-selective fault indication, clear visual signaling directly on site, and flexible application options in cable and overhead line networks. Earth fault and short-circuit indicators support industrial engineers in rapid fault analysis and contribute to the high availability of electrical networks.
