A high-voltage current transformer may contain several cores, each with a secondary winding, for different purposes (such as metering circuits, control, or protection). [7] A neutral current transformer is used as earth fault protection to measure any fault current flowing through the neutral line from the wye neutral point of a transformer.
Diagram of center-tapped transformer. In electronics, a center tap (CT) is a contact made to a point halfway along a winding of a transformer or inductor, or along the element of a resistor or a potentiometer. Taps are sometimes used on inductors for the coupling of signals, and may not necessarily be at the half-way point, but rather, closer ...
A current clamp uses a current transformer with a split core that can be easily wrapped around a conductor in a circuit. This is a common method used in portable current measuring instruments but permanent installations use more economical types of current transformer.
The transformer winding voltage ratio is equal to the winding turns ratio. [6] An ideal transformer is a reasonable approximation for a typical commercial transformer, with voltage ratio and winding turns ratio both being inversely proportional to the corresponding current ratio.

Combine the vodka, cranberry juice, lime juice, and triple sec in a pitcher filled with ice. Stir well until chilled, then strain through a fine mesh strainer or slotted spoon into 4 martini or ...
This is a common method used in portable current measuring instruments but permanent installations use more economical types of the current transformer. Specially constructed wideband CTs are also used, usually with an oscilloscope , to measure high frequency waveforms or pulsed currents within pulsed power systems.
