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”

Practical 400 Hz use Cases for Aviation Teams
Published by Dranetz Technologies, Inc. Below are three situations aviation teams often face, and how the HDPQ Xplorer 400 helps resolve them. Jetway keeps resetting when an aircraft connects What’s happening: During bridge movement or aircraft power-up, the 400 Hz supply dips. Sometimes it is a brief sag, other times a fast transient that trips protection.Continue reading “Practical 400 Hz use Cases for Aviation Teams”
400Hz Monitoring – Aviation Applications
Published by Dranetz Technologies, Inc., Application Note INTRODUCTION Most of the world distributes power at 50Hz or 60Hz. However, there are certain specialized applications that distribute power at other frequencies. Applications such as aviation, naval, and others distribute power at 400Hz to improve system efficiencies. 400Hz applications can be a challenge for the end user since mostContinue reading “400Hz Monitoring – Aviation Applications”
The Critical Role of Power Quality Evaluation in Solar Installations
Published by Dranetz Technologies, Inc., Application Note EXECUTIVE SUMMARY As solar photovoltaic (PV) systems become more prevalent in commercial and industrial environments, the emphasis on financial return and concise performance expectations has rightly intensified. However, one often-overlooked aspect of solar deployment is the comprehensive evaluation of power quality (PQ)—both before and after installation. By identifying existing gridContinue reading “The Critical Role of Power Quality Evaluation in Solar Installations”
Planning and Performing a Power Quality Survey
Published by Dranetz Technologies, Support – Technical Documents, Application Note, website: dranetz.com, 800-372-6832 (U.S & Canada) +1-732-287-3680 (International). INTRODUCTION The power quality survey is the first, and perhaps most important, step in identifying and solving power problems. Power problems can harm equipment performance and reduce reliability, lower productivity and profitability, and even pose personnel safetyContinue reading “Planning and Performing a Power Quality Survey”
Understanding Telephone Interference Factor
Published by David Horning, March 2013. Power Monitors, Inc., White Paper: Understanding Telephone Interference Factor Abstract. Harmonic distortion that is produced from power conversion systems can cause interference on analog telephone lines. The degree of telephone interference can be expressed in terms of the Telephone Interference Factor (TIF). This white paper will discuss how interference isContinue reading “Understanding Telephone Interference Factor”
