dans le domaine inductif
Explanation:
Le moteur peut fonctionner avec un facteur de puissance inductif (sous-excité) ou capacitif (surexcité). Le graphe du facteur de puissance possède donc deux domaines : inductif et capacitif, et il s'agit ici de prodéder au test dans le domaine inductif.

Explanation:
My take.

I think a word is missing. "this test should be carried out on the lagging side"...

côté en retard (i.e. dans le quadrant de l'angle en retard)


Explanation:
I already said that I know lag angle, lagging current, lagging load and lagging phase (angle).
Here: the phrase "This test should be carried out lagging side of generator capability curve" relates directly to generation of electricity and shifting of the lagging phase by over- or under-excitation of the stator field.

Excitation
An induction machine requires an externally-supplied armature current. Because the rotor field always lags behind the stator field, the induction machine always "consumes" reactive power, regardless of whether it is operating as a generator or a motor.
https://en.wikipedia.org/wiki/Induction_generator

There is also a difference between a lagging and leading power factor. The terms refer to whether the phase of the current is leading or lagging the phase of the voltage. A lagging power factor signifies that the load is inductive, as the load will “consume” reactive power, and therefore the reactive component Q is positive as reactive power travels through the circuit and is “consumed” by the inductive load. A leading power factor signifies that the load is capacitive, as the load “supplies” reactive power, and therefore the reactive component Q is negative as reactive power is being supplied to the circuit.
https://en.wikipedia.org/wiki/Power_factor#Lagging_and_leadi...

Le compensateur synchrone est un appareil utilisé dans le domaine industriel et des réseaux de distribution électrique. Il s'agit d'un moteur synchrone tournant à vide sur un réseau, non entrainé par une machine tournante. Il fournit alors de la puissance réactive au réseau, c’est-à-dire une charge capacitive, sans que les effets secondaires des bancs de condensateurs pour courant alternatif entrent en jeu.

The reactive power output of a synchronous generator is constrained by several factors:
armature current limit, field current limit, and end region heating limit [1]. Each of these limits are modeled as circles in the active-reactive power output plane. The machine must operate within the intersection of these circles. The generator must also operate within maximum and minimum active power limits imposed by the prime mover.

(You will see from fig. 1 that reactive power is supplied for lagging angle and consumed for leading angle)

"This test should be carried out on the lagging side of generator capability curve" =>
"Cet essai doit être effectué sur le côté en retard de la courbe de capacité du générateur", mais both expression sont difficiles à comprendre.
On peut dire simplement :
"Cet essai doit être effectué si l’angle de phase est en retard"
