Harmonics(in electrical systems)

• https://www.fluke.com/en/learn/blog/power-quality/how-to-find-harmonics-in-electrical-systems
  
•  Overheated transformers and tripped breakers could be a sign of harmonic issues, which occur when non-linear loads that draw current in abrupt pulses, rather than in a smooth sinusoidal manner, cause harmonic currents to flow back into other parts of the power system.
• This value of THD in terms of power quality health is most often applied to the voltage. Guidance states that the voltage harmonic effects should be less than 8 percent relative to the fundamental. Values above the stated 8 percent should be investigated further.

 

This document solution is the best approach.

PowerFactor VS CosPhi

You Can read this article. In summary;

• CosPhi results from the ratio of effective power (P) to fundamental apparent power (S1). 

• PF; results from the ratio of effective power (P) to total apparent power (S) from fundamental and harmonics.
  

 

Beaglebone Black Notes

1. When you need enabling uart of beaglebone black. read this site first and read this site

      2. Minicom is a great tool for command line serial port testing.

    " minicom -b 9600 -D /dev/ttyO1" --> 9600 8N1 open Uart1 BBB :)

Altium Designer Notes

1.  Q --> change to imperial to mm or reverse is true
2. TAB --> open properities panel
3. After selecting the component, press the left key of the mouse and click the J+R character on your keyboard. This shortcut helps to which you select things and move to the center.  
4. CTRL+M --> Measurement , SHIFT+C clear measurements value view. 
5. Press G character to change grid size.
6. Place->Directives->No ERC for closing unused pins
7. ON/OFF  if you want to top line to "ON" a straight line, use this technique.
   

 

Note: when you need a specific shortcut about Altium Designer. please see this video for remembering something. 

 

 

Quectel M66 Notes

 1- if you don't want to AT command back to you:)

Command: ATE0\r     (for reopen-> ATE1\r)

Economic notes

1- read below article for learning "Simple Moving Average(SMA)" and "Exponential Moving Average(EMA)". this article is simple calculation for future prediction.
