Synchronous Reactance (in a generator analysis domain) is and equivalent series per-phase inductance term (think per-phase winding resistance) and is mainly composed of the machine's per-phase leakage inductance (equivalent series inductance of primary and secondary flux leakage) and armature reaction (distortion in flux introduced by an armature current in a machine, once again on a per-phase basis; described as a series inductance). L_SyncReac=L_leakage+L_ArmatureReaction. That sort of touches the surface of synchronous reactance.

What does capacitive reactance oppose?
Inductive reactance.
What is the symbol for inductive reactance?
Inductive reactance does NOT have it own sign or symbol. Rather, it uses Ohms as a quantifier. But Capacitive reactance ALSO uses Ohms as a quantifier. Fortunately, 1 Ohm of Inductive reactance is cancelled by 1 Ohm of Capacitive reactance at the same frequency of measurement.
Difference between synchronous generator and synchronous motor?
ASYNCHRONOUS is a mode whereby events happens irregardless of control. SYNCHRONOUS are this same events but controlled by a timing and/or control
What is the use of reactance relay?
reactance relay is used for distance protection of the transmission line....
How do you write out an equation used to find the inductive reactance ant the capacitive reactance?
Xc(capacitive reactance) = 1/(2piFC)XL(inductive reactance) = 2piFLWhere pi=3.14etc.,F=frequency and C and L are capacitance and inductance.Please pardon lack of proper symbology.
What is synchronous reactance in alternator?
The overall reactance of the armature winding is the sum of its leakage reactance plus fictitious reactance, which is known as synchronous reactance (Xs).Xs=XL+Xarwhere XL and Xar are in Ω/phase. Therefore, Xs is in Ω/phase.The impedance of armature winding is obtained by combining its resistance and its synchronous reactance.
What has the author Kamal Koshal written?
Kamal Koshal has written: 'Direct and quadrature-axis synchronous reactance measurement'
In order to reduce inductive reactance what devices are normally placed on transmission or distribution lines?
== == Add a capacitor or a synchronous motor or a phase advancer to the transmission line so that it can nullify the effect of inductive reactance since the above elements gives capacitive reactance. Doing this also improves the power factor.
What is the formula for excitation voltage?
E=Vt + Ia jXS Where E excitation voltage Vt Terminal voltage Stator Current Ia Xs synchronous Reactance
What is the unit of inductive reactance?
Inductive reactance, as well as capacitive reactance, is measured in ohms.
What does capacitive reactance oppose?
Inductive reactance.
What is synchronous machein?
mainly alternator,synchronous motor comes under the synchronous machine.a synchronous motor is not a self starting motor.if a synchronous motor moves with more than synchronous speed then it acts as a synchronous generator.
What is the inverse of reactance?
The reciprocal of reactance is susceptance, expressed in siemens.
What are the letters for Inductive Reactance?
The symbol for inductive reactance is XL.
What is difference between synchronous motor and synchronous condenser?
a synchronous condenser is over excited synchronous motor under no load
What is the meaning of synchronous in Tamil?
The meaning of synchronous in Tamil is "ஒருவரின் நடப்பு அல்லது இறுதிவார்த்தைக்கு பின்பற்றுவது."
How does doubling the frequency effect the reactance of an inducter and capacitor?
for inductor, reactance XL = 2*pi* f *L, if frequency doubles then reactance increase. But for capacitor, reactance Xc = 1/(2*pi*f*C). In this case if frequency doubles the reactance decrease.
