i Built this DIY AC energy meter which can measure AC voltages and current upto 100A. this meter uses a non invasive current transformer and a display unit to display the readings. it also has many other functions such as total power and energy consumed, power factor, and ac frequency.
using this device i was able to measure the power consumption of my newly built 3d printer, which will be useful for an upcoming project.
