PDL 650

PDL 650 is a portable device designed for precise measurement of power losses in three-phase electrical networks. It is used to assess load losses, no-load losses, and efficiency of transformers and power equipment. The system provides high-accuracy measurements using advanced phase compensation and harmonic rejection technologies. Designed for field environments, PDL 650 delivers stable results even under distorted waveform conditions commonly found in distribution networks. Its user-friendly interface and automated reporting functions support efficient workflows during commissioning and maintenance. The device pairs seamlessly with OMICRON’s primary testing equipment for comprehensive transformer performance evaluation.
