Hi,
Presently we are using External CT and it will be connected to Microcontroller Analog Port to measure the Secondary coil Voltage to calculate the energy consumption.
But we need to design the Energy meter device to Monitor the various power parameters like Voltage, Current, Power, Frequency, Power Factor and many more Harmonics.
Kindly Provide any reference design and suggest us the suitable IC with Evaluation boards to develop the Product.
Thanks and regards,
Naveen K
