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.
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.
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 ...
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.

MADRID (AP) — Kylian Mbappé made some peace with Real Madrid’s fans. Mbappé scored in Madrid's 2-0 win over Getafe in the Spanish league on Sunday to help ease the pressure on the France star.
The Dodgers hold a 2-0 series lead over the Yankees entering Monday's Game 3. Ohtani had one hit and scored a run in their Game 1 win, and he didn't have a hit Saturday.
Standard Scott Connection 3 φ to 2 φ. Assuming the desired voltage is the same on the two and three phase sides, the Scott-T transformer connection (shown right) consists of a centre-tapped 1:1 ratio main transformer, T1, and a √ 3 /2(≈86.6%) ratio teaser transformer, T2. The centre-tapped side of T1 is connected between two of the phases ...
