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”
