Sometimes, the face of your meter includes information such as the wattage and the identification number. So just complete that calculation for each segment until the table is complete for 1 full cycle. The circuit diagram of three-phase voltage measurement system is given below. Single & Three Phase Line kVA calculator is an online tool used in electrical engineering to measure the unknown quantity by two known quantities applied to the below formulas for single phase and three phase connection. Single-phase voltage is half the voltage tested between the line pairs. Your support helps wikiHow to create more in-depth illustrated articles and videos and to share our trusted brand of instructional content with millions of people all over the world. As voltage pushes the electrons to create electrical current then the electrons change direction either 100 or 120 times per second. Then the south pole comes [1] directions which is of no use to us. Three Phase AC Voltage. That’s how we get more power from the supply. For example: North America uses ~120V, Europe uses ~230V, Australia and India uses ~230V and the UK uses ~230V.These are the standard voltages set by each countries government regulations.

When the generator starts, the north and south pole of the magnet are directly between the coils so the coil doesn’t experience any effect and no electrons move. and why do we get these sine waves? If you look on your electrical devices you’ll see either 50Hz or 60Hz that’s the manufacturer telling you what type of supply the equipment needs to be connected to. These voltages are known as the RMS value or the Root Mean Squared value. This image may not be used by other entities without the express written consent of wikiHow, Inc.
