We got a new metering system that monitors power quality on campus. My question is when I am looking at kvar vs kw what do I look for as being a problem? for example, one of our buildings is using in real time 11kw and has 1kvar. Also when is harmonics a problem? Another one of our buildings has a total harmonic distortion in volts of 1.7% and in current 17.5 % on 1 phase in a 3 phase system. This meter also measures harmonic in each level. What is exceptible in each level? I am in a learning process in understanding power quality so any help will be great.
