6 FAQs about [Series-shunt reactor capacitor]

What are the effects of shunt reactors and series capacitor banks?

III. LINE DIFFERENTIAL APPLICATION AND SOLUTION The shunt reactors and series capacitor banks introduce impacts on the protections, such as line distance relay, line current differential relay, and directional relay, etc. .

Why is a series capacitor used to test an inductive shunt reactor?

It could be said that series capacitors produce more net increase of voltage which produces more voltage drops in the system. Conclusions An emulator is used to test an inductive shunt reactor in the cases of high voltage transmission lines in order to stabilize the voltage during changes of the load.

Is a shunt capacitor better than a series capacitor?

It may be noted that for the same voltage boost, the reactive power capacity of a shunt capacitor is greater than that of a series capacitor. The shunt capacitor improves the pf of the load while the series capacitor has hardly any impact on the pf Series capacitors are more effective for long lines for improvement of system stability.

What is a shunt reactor?

Two commonly used shunt reactors are emulated and these are the gapped core type or the magnetically shielded air core type. These designs keep the impedance of the reactor fixed. The impedance in the transmission line is kept at a constant value in order to avoid harmonic current which can be generated because of any over voltage.

What is a shunt capacitor?

Shunt Capacitors Shunt capacitors, that is, capacitors connected in parallel with lines, are used extensively in distribution systems. Shunt capacitors supply the type of reactive power or current to counteract the out-of-phase component of current required by an inductive load.

Which is better shunt reactor or series reactor?

Example: Reactor Earthin g system, lighting choke, VFD filters, wave shaping circuits etc. Less cost than shunt reactor. Shunt reactor limits the over voltage but series reactor limits the high current.
