Week 13 (5 May - 11 May 2014)

Title: Project progress (FYP 2)
Objective: Result
Content: On week 13, I continue with calculation of Voltage drop. For voltage drop I call back all the value that I get which is the cable size, IB, Length and also the TVDR. The formula that I use is:

 Vdr = (TVDR x P.factor) x IB x Length / 1000

Voltage drop is a excessive voltage drop in a circuit can cause the electrical equipment will be damage or burn. It causes the load to work harder with less voltage pushing the current. If current and impedance increase, so the voltage drop also increase.The %voltage drop is the permissible value of voltage drop that only has along the cable. Based on IEE regulation there is no large more 4% per cable. More length the cable, more voltage drop will have.

The result that I got from all the calculation and the data that user key in is:

  Reset button is used when the user want's to clear back all the data that they key in. The coding is:

set(handles.edit1,'string','');
set(handles.edit2,'string','');
set(handles.edit3,'string','');
set(handles.edit4,'string','');
set(handles.edit7,'string','');
set(handles.edit8,'string','');
set(handles.edit9,'string','');
set(handles.edit10,'string',''); ...........>>>>>>and so on...

When cursor is brought to button, the tooltip will appear to let user know what is it. The coding is:

B = sprintf('It,min= CURRENT CARRYING CAPACITY **Click to get the value of It,min');
set(handles.pushbutton3,'TooltipString',B)
