The ACR Systems PowerWatch (PWV-002-U) Voltage Disturbance/Power Quality Analyzer and Event Recorder with 32 KB Memory and 220V United Kingdom Plug is your first line of defence against power quality problems. Simply plug it into any power receptacle and begin monitoring and recording essential voltage disturbance information - surges, sags, outages, impulses, dropouts, and frequency variations. Set up your pre-determined disturbance threshold values or use the industry standard default values using PowerWatch software. No wiring or dangerous connections are required.

PowerWatch Software

This powerful and easy-to-use power quality analysis software program is developed exclusively for ACR's voltage disturbance recorder, the PowerWatch. With no programming hassles or complex menus, setup and downloading occurs in seconds. Connection is simple: plug the optical interface cable (LIC-101 cable) into the serial port of your computer and point the other end to the optical port on the PowerWatch. Communication begins immediately. Detailed site reports are displayed for every voltage disturbance event recorded including:

With the Quick Summary option, all events are summarized and displayed individually in a bar graph format. This helps determine power quality trends quickly and effectively. The Event Distribution Graph plots the magnitude of events against duration on a logarithmic scale, allowing you to determine the importance of the data (a single random event may not be as important as a cluster of events). The Event Distribution Graph also helps determine what kind of power quality problems you have as all 4000 events can be plotted on this graph. You have the choice of analyzing hot-to-neutral or neutral-to-ground events or showing both in different colors. The CBEMA Curve can be used to determine the importance of each event.
