Phase shift for current limitting reactor

[Schwatzernov]

Dear All,

Do anyone have experience with using current limitting reactor for limiting short circuit current in the system.
Someone said that using this reactor will cause 90 degree phase shift and synchronizing can not be possible without using some device to compensate this phase shift back to zero degree.
Is this understanding correct ?
Anyone, please advise.

Thank you

Since current through the reactor is zero before syncronizing, there is no phase shift. So no need to use any "device" to "re-phase" the system.

You have to consider the impedance and the X/R ratio of the entire circuit. At normal current levels the impedance of the load will predominate and determine the power factor. (phase shift of the current.) It is only when a fault shunts all or part of the load and the currents are extremely high that the reactor predominates in determining the phase shift. If you were to "compensate" for the phase shift (possibly with capacitors) you would defeat the purpose of the current limiting reactor, at considerable expense.
