Measure current, voltage, and impedance for AC Circuit

Good morning-

(Newbie here) I understand I can use Simulink to represent a circuit and measure current, voltage, and impedance of that circuit. Is there a step-by-step somewhere on what tools (toolbox?) can enable this and how to install / use?

This feels very basic, but I need some help to get me pointed and started in the right direction. Thank you!

Hi, BAM.

You can measure current and voltage of an AC circuit by using "Simscape / Electrical / Specialized Power Systems / Fundamental Blocks / Measurements" - Current Measurement and Voltage Measurement blocks.

You may find the information of Current Measurement and Voltage Measurement blocks from:

(1) https://www.mathworks.com/help/physmod/sps/powersys/ref/currentmeasurement.html

(2) https://www.mathworks.com/help/physmod/sps/powersys/ref/voltagemeasurement.html

For example, a simple AC circuit can be measured in term of impedance, current and voltage by using the respective measurement blocks as shown below:

*The figure is sourced from Mathworks MATLAB/ Simulink.

Kah-

Thanks for that, very helpful. I installed Simscape. How do I find / run it? Is it started through the command window?

Hi, BAM. You can create or open a Simulink model, and in the Simulink environment, click on the library browser and search for "current/voltage/impedance measurement", and the blocks in Simscape should appeared in your search result. Just drag and move it into your Simulink model. Hope this helps.

Thank you Kah- I see this now. Give me some time to play with this and I'll follow up. I appreciate your help.
