A dedicated and classified control panel receive 480 VAC @60 HZ (Input) for provide power to all control systems (PLC, OIT, I.S. barriers, etc)and
some motor (One of 75 HP, 1 of 10 HP). The electrical measurement executed with electrical data logger installed on the three phase of the incoming power were the followings: Power Factor Range (.19 to .31), Harmonics (7th)=1.67 %.
Questions: Do the values mentioned above can affect PLC power and Instrumentation power supply performance?
