For that, the need for the development of a compact and highly efficient solid-state transformer is becoming a critical task in-order to integrate the current AC grid with the new renewable energy ...

Abstract: Accurate diagnosis of incipient faults in oil-filled power transformers is important in preventive maintenance of transformers. Dissolved gas analysis (DGA) is an effective tool to diagnose ...

The associated power quality issues of these adjustable speed drives, especially harmonic currents, adversely affect the power distribution transformers by increasing their losses and decreasing their ...

Abstract: A finite element method is presented to compute the electromagnetic field and hence the temperature rise in complex three-dimensional structures such as power transformers. The temperature ...

As the U.S. presidential campaign reaches its November 5 climax, Republican candidate and former president Donald Trump has escalated his war on the free press, verbally attacking the media more than ...

Abstract: In contrast to traditional 60 Hz transformer, solid state transformer (SST) offers power flow control, integration of renewables and maintaining grid stability in high renewable penetration ...

The company said the most common cause of transformer failure is overloading and unauthorised connections. The notice relates to land LR NO. 113044/R NAIROBI situated in Komarock, Nairobi county.

Abstract: In traditional applications such as machine field excitation, where power transfer from stationary to rotary side is needed, contact slip rings are often adopted. However, this kind of slip ...

This paper investigates the applicability of operational modal analysis (OMA) to extract modal parameters of transformer windings under random excitations. Firstly, random vibration signals are ...

Abstract: This paper discusses the suitability of vegetable oil as an insulating medium in power transformers. A high flash point and very good environmental compatibility compared to conventional ...

Abstract: This paper studies physical consequences of unobservable false data injection (FDI) attacks designed only with information inside a subnetwork of the power system. The goal of this attack is ...

Abstract: This paper proposes a multiport power electronic transformer (PET) topology with multiwinding medium-frequency transformer (MW-MFT) isolation along with the associated modeling analysis and ...
