Fluke VR101 Voltage Event Recorder
et up, plug in, download, and analyze
Homes, offices, hospitals, and factories depend on electronic devices. And electronic devices depend on good power quality. The Fluke VR101S is the perfect system for catching sags, swells, transients, outages and frequency variations on line voltage at receptacles, where the most sensitive loads are connected. The VR101S is a starter system that includes a compact VR101 event recorder, an optical interface cable, and EventView software that turns your PC into a power quality reporting tool. Additional VR101 event recorders can be purchased individually, so you can monitor several voltage conditions at multiple locations at once.
Software for Power Distribution Systems
International standards define a number of different power distribution systems, TN or IT.
1.TN systems: The most frequently used power distribution systems worldwide are the TN systems. Three phase power distribution with a common earth connection back to the supplying transformer.
2.IT system: The IT-system (Isolated Terra) is in use in Norway (90%), Belgium and some other countries. The differentiation lies in the way the Protective Earth (PE) and the Neutral are treated.
