My design frequency is 2080Hz. I applied the same while defining windings as Vpeak*sin(2*pi*2080*time)
but my input waveform appear like this. Seems frequency is less than that.February 4, 2021 at 11:10 amNavya CAnsys EmployeeHi,nThat should not be the case as you are just plotting the input current.nCan you please provide some screenshots that explain how you set up your model, solution setup, and excitations?nIt may happen because of the large timestep in your solution setup. Reduce the timestep and check.nAlso, are you using any external circuit excitation?. if so please provide information on the same.nnRegardsnNavyannFebruary 5, 2021 at 5:19 amSherinSubscriberThe above is the model of my work. Winding are excited by taking terminals in the YZ plane. Voltage excitation is given with number of conductors as one and excited with Vpeak*sin(2*pi*2080*time), where Vpeak=89V.nI have given solution setup like this.nPlease suggest any modification required in this for working at 2080Hz.February 6, 2021 at 10:08 amSherinSubscriberI changed step time small value than entered above and got high frequency input signal. Thanks for the help.nI changed the coil assembly as foil type winding with two turns and terminal connection as shown below.nGiven input voltage at any specific instant (at wt=90) then entered Va=325V, Vb =-162V and Vc=-162V. It worked and flux density distribution found as uniform, but input current taken from the source is in kilo amperes. Normally in open circuit condition current requirement is less, but how my assembly takes kA of current??? (Transformer rating is 1000kVA, 11kV/415V)nViewing 3 reply threads
