Core losses of transformers motivate many engineers and scientists to design implement different for their specific aims. Since there exists a growing interest on high frequency applications in today’s world, optimization studies magnetic fluid core transformer (MFCT), having an easy cheap production approach applications, are considered the present paper. The desired should operate more effici...

Signal injection method (SIM) is widely applied to the insulation parameters’ measurement in distribution network for its convenience and safety. It can be divided into two kinds of patterns: injecting a specific frequency signal or several frequencies’ groups, and scanning frequency in a scheduled frequency scope. In order to avoid the disadvantages in related researches, improved signal injec...

Recently, some researchers have begun to adopt the Transformer combine or replace widely used ResNet as their new backbone network. As captures long-range relations between pixels well using self-attention scheme, which complements issues caused by limited receptive field of CNN. Although trackers work in regular scenarios, they simply flatten 2D features into a sequence better match Transforme...

High-frequency current transformers (HFCT) are well suited as sensors for measuring transient signals on power cables, such partial discharges (PD). If the HFCT is designed and its measurement bandwidth matches of signal to be measured, high sensitivities can achieved. However, optimizing design a specific difficult task because various parameters affect transfer function. In addition, there li...
