<p>The invention relates a system for providing information about installation quality of load elements (30). Performance of power distribution systems, such as Power- over-Ethernet (PoE) systems, is depending on the overall system installation performance like quality of the connections (10) between power control devices (20) (e.g. PoE switches) and the powered load elements (30) (e.g. luminaires), Cat5/6 cable quality, cable type, length of the cables, aging of the connections, etc. The proposed system is able to provide feedback and to judge system installation performance at t=0 and over time.</p> |
