Analysis of relay protection action of grounding fault of no-load charging of a 330 kV transformer

Gong-kuang zidonghua, 2013
In view of problem that a 330 kV start-up standby transformer took place relay protection action in no-load charging, the paper indicated that the action was caused by grounding fault of A-phase current transformer through analyzing charging current ...

The X-ray transform for currents

Differential Geometry and its Applications, 2003
The X-ray transform, mentioned in the title, was introduced, but not under this name, as early as 1938 by \textit{F. John} [Duke Math. J. 4, 300--322 (1938; Zbl 0019.02404)]. A compactified version associates to each smooth function \(f\) on the three-sphere \(S^3\) a smooth function \(\phi\) on the real Grassmannian \(\text{ Gr}(2,\mathbb R^4)\).

A novel measurement‐protection‐integrated current transformer based on hybrid core and magnetic field sensor

IET Electric Power Applications
Current transformers (CTs) are widely used for energy metering, relay protection, condition monitoring and control circuits. However, CT saturation may lead to non‐negligible measurement errors and relay malfunctions, posing a threat to the stability and

A New method for winding connected to the ground internal fault localization in the transformer using the extended Kalman Filter

Franklin Open
Inrush current in the transformer may assume as fault current for the protective equipment. Thus, it is important to distinguish the inrush current from the internal fault current in the transformer.
