The latest version of DCLC, DCLC 3.35, resolves the issue with periods and commas. In DCLC 1.0, the use of periods or commas as a separator could vary depending on both the Windows OS version and the MS Word version.

Figure 1 - Conversion of a current source into an equivalent voltage source

If the circuit contains a current source(s), and the loop current method is selected as the calculation method, all current sources must be converted into equivalent EMF sources. An example taken from the user manual is shown in Figure 1 above.

The text fields opposite VA=, VB=, and VC= indicate the effective voltage/EMF values ​​of the three-phase source. If you have specified peak voltage values ​​(Vpeak, which is not standard, as RMS values ​​are usually specified), then they must be converted to RMS values. In AC circuits, the effective value is equal to the peak value divided by the square root of two, that is:

Vrms=Vpeak/√2

and accordingly

VA=VB=VC=Vpeak/√2

If you have not phase voltages but line voltages as the initial data, that is, you have: VL=VAB=VBC=VCA=480 V. In this case, knowing the line voltages, determine the phase voltages using the formula:

VP=VL/√3

VP is the phase voltage, VL is the line voltage In this particular example, this will be equal to:

VP=480/√3=280 V

Thus, as initial data you specify: VA= VB=VC=VP=280 V.

To generate a program report in Microsoft Word format, Word itself must be activated. If you use MS Word without activation, the report may be interrupted by a window prompting you to activate the program.

Figure 2 - DCLC warning about a missing dll file

When working with DCLC 1.0, 2.0, and TPC 1.0, I've encountered instances of a warning about a missing DLL file. The reason is simple: DCLC 1.0, 2.0, and TPC 1.0 use DLL library files (MatNet.Numerics.dll and Complex.dll) to perform mathematical calculations. The programs are supplied in archives with all the necessary DLL library files, but for some reason, when this warning occurs, the DLL files are deleted from the program's root folder. The solution is simple: download the program's source distribution, which contains these files. Therefore, do not delete any files from the root folder; they are also necessary for operation.
