    en.wikipedia.org/wiki/IEEE_1451

    IEEE 1451 is a set of smart transducer interface standards developed by the Institute of Electrical and Electronics Engineers (IEEE) Instrumentation and Measurement Society's Sensor Technology Technical Committee describing a set of open, common, network-independent communication interfaces for connecting transducers (sensors or actuators) to microprocessors, instrumentation systems, and ...

    Frequency Range: 1.6 to 59.999 MHz; Net Presets: 75, fully programmable; Frequency Stability ±0.5 x 10 –6; Emission Modes: J3E (single sideband, upper or lower, suppressed carrier telephony), H3E (compatible AM single sideband plus full carrier), A1A, J2A (compatible CW), selectable; F3E (FM) RF Input/Output Impedance: 50 Ω nominal, unbalanced

  4. Variable reluctance sensor - Wikipedia

    en.wikipedia.org/wiki/Variable_reluctance_sensor

    A given VR-sensing system has a definite limit as to how slow the target can move and still develop a usable signal. An alternative but more expensive technology is Hall effect sensor. Hall effect sensors are true zero-rpm sensors and actively supply information even when there's no transmission motion at all.

  5. Rogowski coil - Wikipedia

    en.wikipedia.org/wiki/Rogowski_coil

    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). A Rogowski coil, named after Walter Rogowski, is an electrical device for measuring alternating current (AC) or high

    en.wikipedia.org/wiki/High_frequency

    High frequency (HF) is the ITU designation [1] [2] for the band of radio waves with frequency between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters).

  7. 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.

    Control Pilot (Current limit): The charging station can use the wave signal to describe the maximum current that is available via the charging station with the help of pulse-width modulation: a 16% PWM is a 10 A maximum, a 25% PWM is a 16 A maximum, a 50% PWM is a 32 A maximum and a 90% PWM flags a fast charge option.

  9. HVDC converter station - Wikipedia

    en.wikipedia.org/wiki/HVDC_converter_station

    An HVDC converter station (or simply converter station) is a specialised type of substation which forms the terminal equipment for a high-voltage direct current (HVDC) transmission line. [1] It converts direct current to alternating current or the reverse. In addition to the converter, the station usually contains:
