A Simplified performance analysis of low-voltage power transmission in small-scale industrial units
Author(s): Klaus Werner Hoffmann and Thomas Heinrich Weber
Abstract: Low-voltage power transmission systems in small-scale industrial facilities often suffer from overlooked inefficiencies that accumulate into substantial energy losses over operational periods. This research investigated the performance characteristics of 400V three-phase power distribution networks across 48 manufacturing units in Bavaria, Germany, representing five distinct industrial categories. Field measurements were conducted from March 2023 to November 2023 using calibrated power analyzers and thermal imaging equipment to capture transmission losses, voltage regulation issues, and power quality parameters. The investigation revealed that average transmission efficiency ranged between 84.6% and 91.2% depending on the industrial sector, with textile manufacturing facilities showing the poorest performance. Cable resistance contributed 21.3% of total losses, while transformer inefficiencies accounted for 30.1%. Harmonic distortion levels exceeded acceptable thresholds in 67% of surveyed installations, primarily due to non-linear loads from variable frequency drives. A simplified analytical model was developed correlating transmission distance, conductor material, and load profile with overall system efficiency. Implementation of recommended optimization measures in a subset of facilities demonstrated potential loss reductions of 18.7% to 24.3%. These findings highlight that straightforward technical interventions, including conductor sizing corrections and harmonic filtering, can yield meaningful improvements in industrial power transmission without requiring infrastructure overhauls.
