Because above 400 volt, this method become expensive than potential Transformer. NOTE: Difference amplifier method is economical for voltage measurement less than 400 volt. Difference amplifier method is more economical than potential Transformer when you want to step down voltage less than 400 volt AC. Potential Transformer can also be used to step down 220 Alternation voltage.But why you want to spend more money? when you can do this with the help of cheap operational amplifiers and few resistors.
To measure 220V AC, you need to step down this voltage.

Program for how to measure AC voltage using PT Alternating voltage measurement.Simulation result of how to measure ac voltage project:.Circuit diagram of how to measure ac voltage using microcontroller.Main components of ac voltage measure project:.In this tutorial, We will discuss ac voltage sensing with two method: But all these tutorials are about measurement of low DC voltage.In this project, you will learn how to measure high AC voltage using PIC16f877A micrcontroller. You have came across many online tutorials on various websites about voltage measurement using different microcontrollers. However, the logic used in this tutorial can be used with other microcontrollers such as 8051, AVR, Arduino, Raspberry Pi, Beaglebone, etc. For this tutorial, we will use the PIC16F877A microcontroller. But for both methods, we will use pic microcontroller ADC to take AC voltage samples. That’s means, in the first method, we will use a voltage transformer to step down 220V AC and in the second method, we will use an operational amplifier as a difference amplifier to step down high AC voltage. One is using a potential transformer and the second one is using an op-amp as a difference amplifier. In this tutorial, we will learn to measure AC voltage using a pic microcontroller with two methods.
