Lanticse, Joshua Lloyd U. BSEE 2A 3 Phase AC circuit problems with Solutions 1. The input power to a 3-phase a.c. motor is measured as 5kW. If the voltage and current to the motor are 400V and 8.6A respectively, determine the power factor of the system?
Step 1. Circuits with more than one Motor. Decide which motor has largest FLI rating.
This course treats the subject of three phase power in detail and in a manner that a reader, well experienced in three phase circuits or otherwise, will find easy to follow. The course considers all of the possible types of three phase circuits - balanced, unbalanced, three wire, four wire, wye and delta circuits.
Take the Three Phase AC Circuits (Electricity and Electronics) worksheet. These questions & answers will help you master the topic!
This course presents the means for calculating currents in the conductors of both balanced and unbalanced three phase circuits. Numerous diagrams and examples are used to illustrate the principles that are involved in relatively simple concepts. Balanced circuits are treated first.
You can use this example to see how the 3-phase power calculator works: A 100 amps motor on a 240V 3-phase circuit with a 0.9 power factor produces 37.41 kW of electrical power. Insert these 3 quantities in the calculator, and you should get the same result.
