hey jraef ...
I need to clarify a few things with you ...
Firstly, u said that if I am to investigate the supply power from the inverter to the motor ... I should be obtaining power factor of about 0.95 throughout the speed range of the motor due to the inverter ... am I right?
Secondly, if I...
hey jraef ...
thanks for your info ... what u said abt the pf of the motor when connected to the line and after when the inverter is connected between the motor and the line is truly useful ... thanks once again ....
hey peebee ...
Thanks for your reply ... seems to clear some doubts of mine ... But I reckon I might have made or mistake or did not actually make myself clearer ... :P
From the main utility of 415V at 50Hz, I have connected a PWM controller which I reckon is what u meant by VFD(Variable...
hey electricpete ...
Sorry for my mistake ...
Actually, from the output of the utility ... it is connected to a PWM controller before it is being connected to a AC Induction Motor ...
Hence, I reckon the THD of the line current is due to the PWM Controller??? ....
As u should know, THD is...
hey guys ...
I have connected an AC Induction Motor and am investigating the line current drawn.
Is the Total Harmonic Distortion of the line current higher when an AC Induction Motor is loaded or when there is no load??? ...
Thanks.
hey guys ...
I would like to know what is the typical power factor at the utility (or mains supply) when connected to an AC Induction Motor??? ....
Is there a difference in the power factor when the AC Induction Motor is loaded or not??? ... If yes, are we to expect a higher power factor when...
