Hello, it has been some time since I have posted, but I remember where to ask a question when I get stumped. I work for a small government and install / maintain traffic signals. These run on 120vac generally and the load is approximately 4 amps (LED optics.) In with the mix of microprocessors is a unit called a conflict monitor or Management Malfunction Unit (MMU.) It is setup to detect among other things, incoming voltage drops and spikes hitting 96vac and 150vac. You may have seen this on the road, the traffic signals go into an All Red, or Yellow flashing pattern. The MMU is usually pretty good at identifying the sourse of a problem, but the last incident happened so fast (nano seconds) it could not record it.
Would someone please recommend a good piece of testing equipment that will monitor incoming utility voltage over a period of time? The longer the better. I have heard terms such as: A Megger might do it, a Platform Quality Demand Analyzer, and Power Quality Analyzer and so on.
My personal opinion is that there are very fast Brown Outs occuring. I just need a piece of equipment that will prove or disprove that.
Thank you in advance,
Dave
