I see that you are trying to log signals from a Simscape electrical circuit and facing an issue where the Simscape is logging extra signals in the “Data Inspector”.
The components “n” and “p” that you observe in the logged signals under the Simscape electrical blocks represent the negative and positive ports of the blocks.
To get a better idea on why extra signals are being logged, select any block for example, the “Inductor” block, go to “description” tab and select “source code” option. Now, the source code for inductor block will be opened, where you can see the signals “i_L”, “power_dissipated” as shown in the image below:
The class for “inductor” inherits from “foundation.electrical.branch”, which contains “p” and “n” as attributes which are instances of “foundation.electrical.electrical”. If you open this file using “edit foundation.electrical.electrical” you will observe an attribute ‘v’ which stores the voltage at that particular node as shown in the image below:
So when you select the option to log all signals these voltage signals at each node will also be logged into the “Data Inspector” these are the extra signals that are shown.
To log only selected signals, you can use the “Selective Logging” feature. To know more about “Selective Logging” you can refer to the following documentation link:
I hope this helps!
