Three-phase modelingOvervoltage suppression measuresShunt reactors are commonly used in substations to compensate the capacitive reactive power of electric power systems. When a vacuum circuit breaker (VCB) switches off shunt reactors, an overvoltage with high amplitude and high frequency (HF) is ...

Figure 2. A single-phase, two-wire system uses a current transformer and voltage transformer. With a single-phase, three-wire system (Figure 3), the total power is the algebraic sum of the two wattmeter readings. Each wattmeter is connected from one of the hot wires to the neutral, and...
The three sequence components of a three-phase signal (voltages V1 V2 V0 or currents I1 I2 I0) are computed as follows: V1 = (Va + aVb+ a2Vc)/3V2 = (Va + a2Vb + aVc)/3V0 = (Va + Vb + Vc)/3 where Va, Vb, Vc = three voltage phasors at specified frequency a = e...
