From minor control trips right down to compressor and transformer failures, harmonics can have an impact on every type of HVAC equipment. Surprisingly, harmonics is something that quite often can be overlooked. Harmonic currents and the electrical distribution system Harmonic currents flow in a circuit at multiples of the fundamental 60 hertz (Hz) frequency. For example, current flowing in a circuit at 180 Hz is the third harmonic (60 Hz multiplied by 3). These currents are not indicated on multimeters and therefore are usually not detected until unusual control and equipment problems start to happen. Comparing these current readings from … Continue reading
