current coilの例文

• The saturation probes contain conventional eddy current coils and magnets.
• A current flowing through the current coil generates an electromagnetic field around the coil.
• The moving system of the instrument consists of two vanes that are magnetized by the current coil.
• The type of meter described above is used on a phase configurations use additional voltage and current coils.
• A typical wattmeter in educational labs has two voltage coils ( pressure coils ) and a current coil.
• The current coils are connected in analog wattmeters, the potential coil carries a needle that moves over a scale to indicate the measurement.
• For example, a meter was previously used for four wire services containing two potential coils and three current coils and called a 2.5 element meter.
• The device consists of a pair of fixed coils, known as " current coils ", and a movable coil known as the " potential coil ".
• When the AC polarity reverses, the eddy currents in the disc and the direction of the magnetic flux from the current coils both change, leaving the direction of the torque unchanged.
• The current coil similarly consumes a small amount of power in proportion to the square of the current flowing through it, typically up to a couple of watts at full load, which is registered on the meter.
• Similarly, the flux crosses down through the disc to the right current coil where the eddy current flows radially away from the disc center, again producing a torque driving the front of the disc to the right.
• This field passes from the pole of one current coil up perpendicularly through the disc and back down through the disc to the pole of the other current coil, with a completed magnetic circuit back to the first current coil.
• This field passes from the pole of one current coil up perpendicularly through the disc and back down through the disc to the pole of the other current coil, with a completed magnetic circuit back to the first current coil.
• This field passes from the pole of one current coil up perpendicularly through the disc and back down through the disc to the pole of the other current coil, with a completed magnetic circuit back to the first current coil.
• In a split-phase watthour meter the voltage coil is connected between the two " hot " ( line ) terminals ( 240V in North America ) and two separate current coils are connected between the corresponding line and load terminals.
• Assuming power is flowing to the load, the flux from the left current coil crosses the disc upwards where the eddy current flows radially toward the center of the disc producing ( by the right hand rule ) a torque driving the front of the disc to the right.
• Line-to-line loads draw the same current through both current coils and spin the meter twice as fast as a line-to-neutral load drawing the same current through only a single current coil, correctly registering the power drawn by the line-to-line load as twice that of the line-to-neutral load.
• Line-to-line loads draw the same current through both current coils and spin the meter twice as fast as a line-to-neutral load drawing the same current through only a single current coil, correctly registering the power drawn by the line-to-line load as twice that of the line-to-neutral load.
