Due to the stunning advancement of power electronics, DC system is getting immense attention in field research. Protection and hereafter protective devices for application are two vital areas that need be explored developed further. Designing a device such as circuit breaker possesses lot challenges. The main challenge interrupt current which does not have natural zero crossing like AC has. In ...

In recent years, DC power supply and distribution technology plays an increasingly significant role in systems with a low loss large radius. However, the corresponding network protection electric devices cannot satisfy needs of existing network. Based on this, this article, intelligent/energy-efficient leakage circuit breaker based two-phase magnetic nanomaterials detection control is proposed....

The electricity distribution breakdown can be caused the service life and operating frequency of Oil Dielectric Strength (ODS). Hence, it requires a study due to spare part is difficult find. This paper aims test ODS on Circuit Breaker (OCB) 13.8 kV aged between 29 43 years. used ASTM D1816 standard analyze effect oil circuit breaker physical, color strength ODS. For visual D1524 standard. base...

This paper aims to evaluate important factors that affect switching transients overvoltages during transmission line energization. These factors include the number of repetitions to ensure the statistical characteristic of the study, the variation range of the mean closing time of the circuit breaker contacts, the model used for the representation of the transmission line and the influence of t...
