  • Set 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.

    • 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.
    • 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.

    Setup event parameters

    To set up a VR101 event recorder, just enter the event capture limit parameters on your PC and load them into the recorder. EventView software and the optical interface cable make it easy. Then plug the recorder into the outlet you need to test, and leave it — there's no need to leave a computer hooked up. The compact recorder stores any voltage event that goes outside your limits. The VR101 recorder can store up to as many as 4000 events and a flashing LED tells you when events have been captured.

    Analyze data on your PC

    To get data out of the recorder, hook it back up to your computer. EventView software can download a complete history of the events that occurred while the recorder was plugged into the receptacle. The software lets you build a detailed report of sags, swells, transients, outages and frequency variations with time-stamps and durations. Your PC communicates to the VR101 through an optical interface cable. This means the PC and VR101 are insulated from each other for safety. The event recorder is self-powered by a 7-year lithium battery, so it is not affected by power outages. Each VR101 Recorder has its own real-time clock for time-stamping voltage events and is identified by a unique factory-assigned code. With their clocks and ID codes, multiple recorders can be placed throughout a facility to give a complete picture of power quality.

    Safety conformance
