Posted 5 Feb 2020 Has anyone had any issues with dirty power or disturbances from Utility that occur duration the night? Share this post Link to post Share on other sites
Posted 6 Feb 2020 It is quite common for the utility companies to change the power delivered based on demand or power factor. If you are in an area where you and your neighbors are using a lot of power during the daytime, but not so much at night, the power company will compensate for that. The other thing that could be happening is that a plant in your area may have a new piece of equipment that is affecting your plant. The best thing is to get a power analysis done for at least a week and including at least one weekend. With the proper test reports, you could identify if the power is surging or sagging and if there is a harmonic component present. The report would also show you times of the occurrences which will help you and the utility determine the cause of the issues. Your report should include voltage, current, harmonic and power factor. You can conduct these tests at the main source to your plant or in discrete locations, depending on the size of your plant or where the problems are.
