Faults in three-core armored cable lines in distribution networks are frequent, and using only zero-sequence current time-frequency data to identify fault lines has its limitations. To increase the accuracy of cable fault identification, this paper u

The bridge influence line can effectively reflect its overall structural stiffness, and it has been used in the studies of safety assessment, model updating, and the dynamic weighing of bridges. To accurately obtain the influence line of a bridge, an

Nowadays, intermittent energy resources, such as wind turbines, and direct current (DC) transmission have been extensively integrated into power systems. This paper proposes an identifying method for weak lines of novel power systems with intermitten

Abstract Among the various faults of power transformers, winding faults are particularly common. It is known that short‐circuit parameters can reflect the winding condition, so the on‐line identification of short‐circuit parameters is of great

At centimeter wavelengths, single-dish observations have suggested that the Sagittarius (Sgr) B2 molecular cloud at the Galactic Center hosts weak maser emission from several organic molecules, including CH _2 NH, HNCNH, and HCOOCH _3 . However, the
