What is phase angle in 3 phase?
It is known that three phase lines from a transformer of a distribution line are kept at 120 degree phase angle with each other.
What is the phase difference in 3 phase?
Comparison of Single Phase and Three Phase Power Supplies
| Single Phase Power Supply | Three Phase Power Supply |
|---|---|
| Since there is only a single wire, there is only one AC Signal (usually a Sinusoidal Wave) | The three wires in three phase supply carry AC signal of its own and the three signals are 120° apart |
What kind of microcontroller is used for three phase power measurement?
Following are the main components used in three phase ac power measurement system using pic microcontroller. PIC18F4550 pic microcontroller: It is the main part of this project. It is used to measure three phase ac power. It measures current, voltage and phase angle between voltage and current.
Which is an example of three phase voltage measurement?
Three phase voltage measurement has many applications in power as well as electronics field. Three phase voltage measurement system is used to measure voltage of three phase transmission lines, three phase generator, three phase transformer, three phase induction motor and any other three phase device.
Can a three phase meter measure AC power?
It can be used to measure either three phase ac power of transformer or three phase generator. As you know AC power or wattage of any three phase ac equipment is difficult to measure with the help of microcontroller due to non linearity and out of phase behavior of voltage and current wave forms.
How is AC voltage measured in a PIC microcontroller?
After the voltage divider circuit, the Pic16f877a controller is used. Output of voltage divider is connected with analog channels of a controller which can read analog voltage and convert it into digital value. This measured digital value is used to calculate actual ac voltage with the help of mathematical calculation in programming.
