Right Side Calculation

Node 4: (40 0.015 + 1 0.005) 0.15 = 0.09075 (V)

Node 5: (80 0.015 + 2 0.005) 0.25 = 0.3025 (V)

Node 6: (120 0.015 + 3 0.005) 0.15 = 0.27225 (V)

If 0.09075 + 0.3025 + 0.27225 = 0.6655 V x 4.65 V, the conditions are satisfied.

2-3-4 Step 3: Splitting the System into Multiple Power Supplies

Go to Step 3 if the best location for the nodes cannot be calculated from the formulae. In the third step, there are multiple power supplies and the power supply system is split.

HSplitting the Power Supply System

Be sure to use a Power Supply Tap for each power supply when the Network is supplied by two or more power supplies.

Remove the fuses in the Power Supply Tap to split the power supply system.

Once the power supply system is split, return to Step 1 or 2, and determine the best location of the nodes in each system.
