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”

A New Approach to Cross-Bonding in Medium Voltage Cable Lines
Published by Jacek KLUCZNIK, Gdansk University of Technology, Faculty of Electrical and Control Engineering. ORCID: 0000-0002-2328-9180 Abstract. The medium voltage underground cable sheaths are usually bonded and earthed in every substation on the cable route. This results in additional power losses in the sheaths. The paper presents an idea of reducing power losses caused byContinue reading “A New Approach to Cross-Bonding in Medium Voltage Cable Lines”
Semi-Analytic Calculations of Overvoltages caused by Direct Lightning Strike in Buried Coaxial Cable
