In simple reactive circuits with little or no resistance, the effects of radically altered impedance will manifest at the resonance frequency predicted by the equation given earlier. In a parallel tank LC circuit, this means infinite impedance at resonance. In a series LC circuit, it means zero impedance at resonance:.
Series and Parallel Resonance
Increased power generation depending on demand, becoming widespread of distributed generation systems connecting to the grid in parallel, and the expansion of network cause the fault current levels to increase in power systems. Fault current limiters are being developed to prevent damages triggered by high fault currents and indirect effects on the network. In normal operation, the SPRFCL that remains passively in the system in series resonance at the main frequency limits the fault current by means of the high impedance shown by parallel resonance when a fault condition is detected with the control circuit. The most important advantages of the SPRFCL are that in all short-circuit fault types, limiting the fault currents with a low amplitude oscillation, restraining the rising rate of fault current and also the sags in PCC common coupling point voltage can be successfully suppressed.

Difference Between Series and Parallel Resonance
In the previous chapter, we discussed the importance of series resonance. Now, let us discuss parallel resonance in RLC circuits. Consider the following parallel RLC circuit , which is represented in phasor domain. Here, the passive elements such as resistor, inductor and capacitor are connected in parallel.
Resonance in AC circuits implies a special frequency determined by the values of the resistance , capacitance , and inductance. For series resonance the condition of resonance is straightforward and it is characterized by minimum impedance and zero phase.
Помогать вскрывать шифры? - Она чмокнула его в щеку. - Как бы там ни было, ты поможешь мне с моей рукописью. - Рукописью. - Да.
Ведя рукой по прохладному кафелю, она наконец добралась до двери и нащупала дверную ручку. Дверь отворилась, и Сьюзан вышла в помещение шифровалки.
