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?
Describe the three-phase load: ZA := 20+j ⋅ω⋅0.06 ZB := 20+j ⋅ω⋅0.06. Describe the three-phase line: ZaA := 10+j ⋅ω⋅0.005. ZC := 20+j ⋅ω⋅0.06. ZbB := 10+j ⋅ω⋅0.005 ZcC := 10+j ⋅ω⋅0.005. Calculate the voltage at the neutral of the load with respect to the neutral of the source: ⋅ π 4. j.
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.
This white paper will go inside the motor and provide a more detailed look into what happens when one phase of the power supply is lost and how Sprecher + Schuh overload relays handle the phase failure. Most of the motors that we encounter are delta-connected squirrel cage induction motors.
Three-Phase Power – Example. Calculate the line-to-line voltage from the line-to-neutral voltage 𝑽𝑽𝑨𝑨𝑩𝑩= 3𝑽𝑽𝑨𝑨𝑨𝑨∠30° 𝑽𝑽𝑨𝑨𝑩𝑩= 156∠14.3°𝑉𝑉. Alternatively, we could calculate line-to-line voltage from the two line-to-neutral voltages. The line-to-neutral voltage at phase 𝐵𝐵is.
