• Detector and probe set (signal injector clamps not included)
• Used on grounded and shorted cables in compliance with EN 50110-1 (DIN VDE 0105-100) for the highest level of safety of the operating personnel
• Suitable for hard-to-reach areas due to the compact design of the signal injectors
• Safe and easy connection
• User-friendly and intuitive operation

Clear phase identification is necessary during the installation or repair of medium voltage and high voltage cables in order to ensure the correct connection of the 3 phases. The FUU-DE has been specifically designed to conduct the measurement according to the European safety standard EN 50110-1, which means all parts to be worked on must be grounded and shorted, including the cable cores to be identified. This ensures enhanced safety for the operating personnel on-site.

Three signal injection clamps are applied around the cable cores or grounding cables. Each signal injector inductively feeds a measuring signal with a specific frequency into the grounded cable. The measuring signals are detected and evaluated at the other end of the cable using the detector. On touching a phase with the measuring tip, the detector will display L1, L2, or L3.

FUU-DE Setup

The signal injectors are specially designed for use in compact switchgear and in narrow spaces. Despite the compact design, the clamps can be used on cables with diameters up to 70 mm. The lithium-polymer rechargeable batteries ensure long operation times and are wirelessly charged within their transport case. The FUU-DE is particularly suited for extra-long cables, such as found on offshore and onshore wind farms, as clear phase identification is possible in cable lengths up to 150 miles!
