AI Thread Summary
The discussion revolves around a neutral current issue in a balanced 3-phase system, where the expected neutral current should be zero. The user reports a small value of neutral current despite the system being balanced, prompting inquiries for more details about the setup. Key specifications include an 80-ohm resistor, a 40F capacitor, and a 4H inductor, with various voltage and current readings provided for both star and delta configurations. Participants emphasize the need for a thorough analysis of the system's loads and connections to identify potential causes for the unexpected neutral current. The inquiry is categorized as coursework, indicating an academic context for the problem.

hi guys
i have juss did my connections on a balanced system and the Nuetral current suppose to be zero.the question is to explain why I recorded a small value of neutral current.
thank hope to hear from you soon.

We certainly need more details in order to be of any help. Is this a 3-phase system where you are detecting some Neutral current? A more complete description of the system and the loads is needed.

Also, is this for homework/coursework, or for work? If it's homework/coursework, I can move this thread to the Homework Help section of the PhysicsForums website (where such questions must be posted).
 
oh yes its a 3 -phase system with an 80 ohm res,40F capacitor and 4H inductor,
star source delta load(Vp =65v,VL =110v,Ip =1.3,IL =2.3,wattmeter =138w)
star source star(Vp =62.5, VL =109, Ip= 0.5, IN= 0, wattmeter 1=60w and wattmeter 2=11w).these are the details .thank you.it is a course work

Thread 'Have I solved this structural engineering equation correctly?'

Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
