Abstract :
This paper documents a case study at an industrial facility that uses a large number of half-controlled heater drives. Voltage and current waveforms, along with harmonic spectrums, are gathered from different locations within the facility. A harmonic interaction problem that caused failures in the pulse width modulated adjustable speed drives (PWM ASDs) that were installed in the existing air handling equipment within the heating ventilation and air-conditioning (HVAC) system are analyzed by using the results obtained from measurements and modeling
