  • Current sensors are able to monitor the current by measuring the drop in voltage for a resistor, which is placed in the direct path of the current. This is often referred to as “shunt resistor current measurement.” The current sensing circuit creates a proportional current or voltage output to the current in the path being measured. With enough effort, sensing motor current over some threshold can be done with analog electronics, even with vacuum tubes if desired. However, using a microcontroller is the obvious and simple way to implement such a control system today.

Abstract: Most circuit breakers sense current. Fuses, for example, protect a circuit by blocking the current when it exceeds a limit. While current-sensing circuit breakers work well for constant DC or RMS supply voltages, power sensing is safer for a variable supply voltage such as the battery in a notebook computer. We can avoid this design conflict using the circuit below: A low-value sense resistor, (R_{sense}), is placed in series with the motor. An op-amp alters the voltage at the gate of the MOSFET to permit a current flow through (R_{2}) such (V_{R_{2}}) is equal to (V_{R_{sense}}). This current also flows through the resistor (R_{3}). A current sensor circuit is a circuit that can sense current going through it. If the current reaches a certain threshold, then an indicator, such as an LED, will turn on. This is not an ammeter circuit, where we know or are measuring the amount of current going through. That's a different thing entirely. This is a current sensor circuit, where if we get to a certain level of current, then the output will turn on. 9.In a motor circuit, which of the following devices provides protection by sensing current? A. Over speed switch B. Overload relay C. Ground D. Resistor. 10. After installing a conveyor belt what must be done before tensioning the belt? A. Test run the belt B. Square end pulleys C. Check drive pulley D. Align motor and reducer Motor protection circuit breakers act as protection devices for electric motors, monitoring the electrical supply in motor circuits of 50-60Hz.They protect against phase unbalances and losses, which are detrimental to motors, offer protection against current overload, and prevent short circuits.

    • There are two types of current sensing: direct and indirect. Indirect current sensing is based on Ampere’s and Faraday’s laws. By placing a coil (for instance Rogowski coil) around a current-carrying conductor, a voltage is induced across the coil that is proportional to the current.
