Ac Current Measurement Circuit Diagram
High measurement accuracy measurable current range from very low to medium capability to measure dc or ac current b disadvantages.
Ac current measurement circuit diagram. A current sensor is a device that detects electric current in a wire and generates a signal proportional to that current. In phasor diagram the current through the circuit i is taken as a reference phasor and hence v2 will be in phase with i while v3 is leads the current by an angle ϕ due to inductive circuit. Connect the secondary side of ct to the points shown on the schematic. This is a circuit diagram of interfacing the current sensor with a pic microcontroller.
The completed project allows ac current to be easily measured as a vdc signal and a microcontroller. The easy way to measure high ac currents is to use a clamp meter but. Cheap ac current measurement. In this tutorial you will learn how to design alternating current measurement system using acs712 hall effect current sensor and arduino uno r3 but you can apply same concept to arduino mega pic microcontroller 8051 microcontroller or avr microcontroller.

In this article. From the phasor diagram v1 2 v2 2 v3 2 2 v2 v3 cos. Three phase ac current measurement using current transformer reference design 2 system description an electric motor is an essential moving element of any system. Alternating current ac circuits explained using time and phasor animations.
Signal conditioning circuit original design by lewis lofin. Ac electricity is ubiquitous not only in the supply of power but in electronics and signal processing. The generated signal can be then used to display the measured current in an ammeter or can be stored for further analysis in a data acquisition system or can be used for the. The generated signal could be analog voltage or current or a digital output.
