Power Quality and Energy Monitoring in Controlled Environment Agriculture in New Jersey, USA, Case Study
Published by Dranetz Technologies, Inc. Website: Dranetz.com SUMMARY Controlled environment agriculture (CEA) relies on advanced technologies such as climate control systems, artificial lighting, and hydroponic or aeroponic growing systems. These systems, in turn, require stable, clean power. This Application Note outlines how a New Jersey-based indoor farming facility addressed persistent HVAC and VFD failures by installingContinue reading “Power Quality and Energy Monitoring in Controlled Environment Agriculture in New Jersey, USA, Case Study”
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”
