The polarity of a CT is determined by the direction in which the coils are wound around the transformer core (clockwise or counterclockwise)...

When a CT is "saturated", the magnetic path inside the CT operates like a short circuit on the transmission line. Almost all of th...

The insulation between the current transformer windings and windings to ground should be checked for dielectric strength while performing a ...

The CT alyser is an insepensable instument for on- site verication of current tansfomer accuracy. The traditional transformer test method is...

The DC winding resistance measurement is an important measurement in accessing the true condition, state and accuracy of a CT. Winding resis...
