My plan is to make a CT meter that requires using a CT to measure AC Voltages and frequency of the main supply..
I know there are couple of tutorials available that fits the purpose but I need a response time of max 50ms. i.e. the CT meter should be capable of taking the sample every 50ms.
Does it require any special CT? would a mcu based CT meter capable to take a sample every 50ms.
Any suggestion on CTs and other parts can help.
that makes sense. Well than it depends on the inductivity of the coil.
As a very rough estimation out of my stomac I estimate at 50 ms inductivity is not the main factor
it just depends on the sampling-speed of your ADC. So you should use something with SPI-interface or high-speed internal ADCs like a teensy 4.0
