Remove the warning You see this warning Dialog box titled DOCWin and saying: "Before use, please pay attention to warnings and instructions. Download this file and use it to replace your current version to get rid of it.
In my case i find it to be referenced at the address B In my case i read: Offset F3C. Now go to the first instruction just below the call, in my case this is instruction is at the line B Click on it and read the offset in the status bar, in my case it reads F Now use any Hex editor to go to the F3C offest and start overwriting whatever code there is with the hex code 90 which coreespond to NOP - or do nothing operation.
You have to do this starting from and including F3C up to and including the byte just before F50, i. Sample 1 - Voltage Drop Voltage drop to network calculation software is as easy as "Hello World" to Microsoft Visual Development Studio, but we have to begin with the small and unimportant to be able to go through the details of the fundamental objects. But Prototypes also setup some of the nework parameters, something which we want to do ourselves right now.
You can have as many generators as you like in the design but you can only have One Utility. The reason for this is that another means another network, with a load flow and a Newton-Raphson calculation of its own. No reason why. Start by putting a Utility and configure its properties as follows: Frequency: 50Hz Rated Voltage: V this will be the Phase-to-Phase voltage in a 3-phase network. Rt: 1 Ohm is the earthing resistance used to calculate the PE cross section based on how much heat is allowed by the chosen standard.
These are the MV objects which cannot be used anymore in this LV design. The most important data here are the short-circuit values. Setting these values is one of the most important things in the design. If they are wrong, DOCWin will not be able to find a suitable breaker for your application. The cables will not be sized properly as well according to IEC "Guide to the short-circuit temperature limits of electrical cables with a rated voltage not exceeding 0.
Tip A very important implication of the short circuit value on the breaker-cable assembly is the tripping speed. This is not good because a very high short circuit current will trip the circtui breaker immediately and hence protect the circuit, but a smaller current will take more time to trip the thermal unit in charge of short-circuits in the breaker, and thus the circuits will suffer sustained heat and may be damaged. This same case is common to UPS. One missed functionality in DOCWin is the automatic check-up of the data in some dialog boxes.
And when you change one value in a data entry box, all related values change accordingly. This is very nice but unfortunately it is not well implemented and in our case for setting the short circuit values for the Utility we might have to set this data one entry at a time, coming in and out of the dialog box and ignoring errors several times as necessary.
Remember that the short circuit value is related to the Phase-to-Phase voltage. There is a help button next to each of these short circuits which allow you to specify their values in any way that is most convenient for you. Use this button to set the short circuit values as follows: Known LLL short-circuit apparent power: 0.
What DOCWin has just silently done is an inhertiance process whereby the new object being placed on the drawing is given the electrical properties of the object to which it is connected.
This way all these items are now three phase. Configuring the cable Double click on the cable to display its properties dialog box. You have to let DOCWin calculate the circuit al least once before access to it becomes available. The Description box lets you give the cable your own feeder reference. As you add and drop objects, the sign number keeps increasing which yields an ugly schematic.
Use the renumbl command to renumber the design. The Sign property is a unique identifier og the object in the design and is used mainly in for Network Configurations and setting selectivity. Description: Lets you give the cable your own feeder denomination. Thermal dimensioning in compliance with: IEC The code you choose to abide by may limit the choice of cables you might take.
For example, later you may not choose a cross section more than mm2 for a conductor if you abide by this default standard. The standard also limits the methods of installation permissible for the cable.
