The ACR PowerWatch has been instrumental in monitoring unexpected voltage drops at traffic light control panels across the city. It has helped us determine precisely where the issue arises – the feed coming from Hydro, breaker in the alley or a problem with the wires from the breaker to the traffic light itself. The UPS systems can only help mask the problem of the voltage drops, however the ACRPowerWatch can help diagnose the issue in real-time.

We were faced with the challenge of Hydro speeding up the frequency to keep up with time clocks, which caused coordination issues with the traffic light’s timing. These small changes in frequency made a cumulative difference over time. With the ACR PowerWatch, it has become much easier to log data and detect voltage disturbances as and when they happen. The PowerWatch is handy as now we do not need to sit with a meter waiting to observe what is happening at the intersection. It is truly a simple, low-cost solution to all your voltage drop concerns.
