Split phase motors One phase is shifted with a large capacitor by ~90 degrees In my application I just had to reverse the wires and the end stop wires PyInstaller Can take your python scripts and make it into a self contained application Useful for non technical inclined people on your team Cross Platform! GUIs Tkinter seems to work well in Win10 and Ubuntu 20 LTS Stephen High voltage low current measurement Tony_W Recommended the ACS37002 Hall effect sensor that can be ground referenced in very high voltage applications 0.85m ohm conductor resistance 4.8kV RMS isolation voltage VCC of up to 6.5V -50 to 50A sensing range Gain selection of 30mv/A to 60mV/A In my situation I would want to monitor 0.1mA or 100uA. With a gain of 60mV/A that would be 60u
