Power Quality Lessons from an Controlled Environment Agriculture Facility
Published by Dranetz Technologies, Inc. Website: Dranetz.com For controlled environment agriculture (CEA) operations, temperature, humidity, airflow, lighting, and CO₂ must stay within narrow limits 24/7 to foster growing conditions for high-value crops. When power quality deteriorates, environmental systems can go off-spec, putting these crops at risk. When HVAC and VFDs began failing unexpectedly, New Jersey CEAContinue reading “Power Quality Lessons from an Controlled Environment Agriculture Facility”
