FUU-DE Phase-Identification System Detector and Probe Set (Signal injector Clamps Sold Separately)
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.
