  2. Current sensing - Wikipedia

    en.wikipedia.org/wiki/Current_sensing

    Fiber optic current sensor, using an interferometer to measure the phase change in the light produced by a magnetic field. Rogowski coil, electrical device for measuring alternating current (AC) or high speed current pulses. Giant Magnetoresistance(GMR): Magnetic field sensor suitable for AC & DC Current with higher accuracy than Hall Effect ...

  3. Hall effect sensor - Wikipedia

    en.wikipedia.org/wiki/Hall_effect_sensor

    In such a case the Hall sensor is mounted in a gap in the magnetic core around the current conductor. [24] As a result, the DC magnetic flux can be measured, and the DC in the conductor can be calculated. Hall effect current sensor with internal integrated circuit amplifier. 8 mm opening. Zero current output voltage is midway between the supply ...

  4. Direct current - Wikipedia

    en.wikipedia.org/wiki/Direct_current

    It is this steady state part that is the DC solution. There are some circuits that do not have a DC solution. Two simple examples are a constant current source connected to a capacitor and a constant voltage source connected to an inductor. In electronics, it is common to refer to a circuit that is powered by a DC voltage source such as a ...

  5. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...

  6. Biasing - Wikipedia

    en.wikipedia.org/wiki/Biasing

    A graphical representation of the current and voltage properties of a transistor; the bias is selected so that the operating point permits maximum signal amplitude without distortion. In electronics, biasing is the setting of DC (direct current) operating conditions (current and voltage) of an electronic component that processes time-varying ...

  7. Signal conditioning - Wikipedia

    en.wikipedia.org/wiki/Signal_conditioning

    Signal inputs accepted by signal conditioners include DC voltage and current, AC voltage and current, frequency and electric charge.Sensor inputs can be accelerometer, thermocouple, thermistor, resistance thermometer, strain gauge or bridge, and LVDT or RVDT.

  8. Rogowski coil - Wikipedia

    en.wikipedia.org/wiki/Rogowski_coil

    A Rogowski coil is a toroid of wire used to measure an alternating current I(t) through a cable encircled by the toroid. The picture shows a Rogowski coil encircling a current-carrying cable. The output of the coil, v(t), is connected to a lossy integrator circuit to obtain a voltage V out (t) that is proportional to I(t).

  9. Current clamp - Wikipedia

    en.wikipedia.org/wiki/Current_clamp

    The clamp measures the current and other circuitry the voltage; the true power is the product of the instantaneous voltage and current integrated over a cycle. Comprehensive meters designed to measure many parameters of electrical energy ( power factor , distortion , instantaneous power as a function of time, phase relationships, etc.), use ...
