To calculate RMS values, electrical power and electrical power factors, the electrical modules are available for different types of networks:

• Delta module

• Star module

• Single-phase module

• Two-phase module

ibaPDA uses the same formulas as ibaAnalyzer to calculate the different electric values. The formulas of the single-line module are the same as the formulas of the star module, with u2, u3 and i2, i3, i4 equal to zero. The following figure shows an example for a delta module.
