The pure inductive loaded system and phasor diagram are illustrated in Fig. 8.3 referring to aforementioned approach. The pure inductive loads, i.e. shunt reactors used in tap-changing transformers and generation stations, do not draw power and δ between load voltage V and source voltage E is zero. is zero.
Since the capacitor voltage V C0 is equal to source voltage, the current component of the TSC will be zero when the capacitor is connected at the peak value of source voltage V m, (α = ±90 ). When the TSC is disconnected from line, the capacitor will be charged to the source voltage and remains at this value.
Lowering the gain of an amplifying stage may also change dynamics because, for example, of a relationship between the input capacitance and voltage gain of a common-emitter amplifier. A further practical difficulty arises in that there is generally no predictable way to change the d-c open-loop gain of available discrete- or integrated-circuit operational …

As microprocessor currents exceed 500 A and slew rate reaches 1000 A/µs, increasing the decoupling capacitance on the motherboard to ensure normal operation of the microprocessor is inevitable because of the limited response capability of the voltage regulator. However, the area of the motherboard used for capacitors is …
Series compensation is the method of improving the system voltage by connecting a capacitor in series with the transmission line. The basic idea behind series capacitive compensation is to decrease the overall effective series transmission impedance from the sending end to the receiving end.
