The ring-type transformer, considered impractical for power transformation because of difficulty in construction and insulation, can now be built easily. Performance characteristics of thisExpand
Transformer Electrical Insulation [Editorial]
This Special Issue of Transactions on Dielectrics and Electrical Insulation is dedicated to transformer insulation because the insulation is perhaps the most critical transformer part. Expand
Past, Present, and Future Challenges of the Marine Vessel’s Electrical Power System
The evolution of the use of electricity in marine vessels is presented and discussed in this paper in an historical perspective. The historical account starts with its first commercial use in theExpand
Low cost digital measurement system for determination of temperature rise in dry type transformer
This paper describes a fully automated method of measuring the cold and hot resistance of a transformer. The measuring scheme was developed by using a code composer studio (CCS) environment,Expand
Developments in Cellulose based Insulating Kraft Paper for Liquid Immersed Power Transformers
Cellulosic materials such as paper have been used in the insulation system of power transformers for a long time due to their ease of manufacture and economical as compared to other materials. ButExpand
Three-phase four-wire dstatcom with H-bridge VSC and star/delta transformer for power quality improvement
A new topology of three-phase four-wire DSTATCOM consisting of a H-bridge VSC (voltage source converter) with a star/delta transformer is proposed for power quality improvement in the distributionExpand
Implementation of Neural-Network-Controlled Three-Leg VSC and a Transformer as Three-Phase Four-Wire DSTATCOM
In this paper, a neural-network (NN)-controlled distribution static compensator (DSTATCOM) using a dSPACE processor is implemented for power quality improvement in a three-phase four-wireExpand

Impacts of Hysteresis and Magnetic Couplings on the Stability Domain of Ferroresonance in Asymmetric Three-Phase Three-Leg Transformers
This paper investigates the stability domain of ferroresonance in asymmetric three-phase three-leg transformers considering magnetic couplings and hysteresis effects of the core. A newly developedExpand
The modular multilevel DC converters for MVDC and HVDC applications
The results demonstrate that these medium voltage and high voltage dc-dc converters are good candidates for the interconnection of dc links at different voltages and thereby make a contribution to future multi-terminal and multi-voltage dc networks. Expand
