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. |
