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!

BAM

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:
