Renewable Energy Collector Transformers

Published by 1. Waldemar ZIOMEK, 2. Krishnamurthy VIJAYAN, PTI Transformers LP, Winnipeg, MB, Canada ORCID: 1. 0000-0002-1216-6513 Abstract. The renewable energy collector transformer (RCT) in a solar station, or a wind farm, transforms the voltage from the collector system to the transmission level voltages. As the primary goal is stepping up the voltage, the RCTContinue reading “Renewable Energy Collector Transformers”

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”

Comparison of Compact Fluorescent to Incandescent Bulbs

Published by Dranetz Technologies, Inc., Case Study With the proliferation of Compact Florescent (CF) lighting, we thought it would be interesting to do a side by side comparison to an incandescent bulb using our new Energy Platform EP1. Not only is it a great demonstration of the capabilities of the EP1 but it’s also an opportunity toContinue reading “Comparison of Compact Fluorescent to Incandescent Bulbs”

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”

High impedance Fault Detection in Low Voltage Overhead Distribution based Wavelet and Harmonic Indices

Published by Enaam ALBANNA1, Alya H. AL-RIFAIE2, Ahmed A. Abdullah AL-KARAKCHI3, Northern Technical University (1,2,3) ORCID: 1. 0000-0002-3974-0116; 2. 0000-0002-7978-2193; 3. 0000-0003-1151-3015; Abstract. High-impedance fault HIF occurs when an energized conductor makes contact with a surface with a high impedance. Conventional overcurrent protection cannot detect this fault due to the low fault current, and thereContinue reading “High impedance Fault Detection in Low Voltage Overhead Distribution based Wavelet and Harmonic Indices”
