Care must be taken to ensure that the relay does not operate from the spill current resulting from unequal CT saturation during motor starting, where the high currents involved will almost certainly saturate the motor CT's. It is common to use a stabilising resistor in series with the relay. The effect of the stabilising resistor is to increase the effective setting of the relay under these conditions, and hence delay tripping. When a stabilising resistor is used, the tripping characteristic should normally be instantaneous. An alternative technique, avoiding the use of a stabilising resistor is to use a definite time delay characteristic. The time delay used will normally have to be found by trial and error, as it must be long enough to prevent maloperation during a motor start, but short enough to provide effective protection in case of a fault.

A stabilizing servo. To quote Blitzwing:Careful you clobber clad klutz! You stepped in something! But with a few dancing lessons you'll be light on your stabilizing servo's like me!
A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).
A series dropping resistor is a resistor that limits the amount of current flow in a circuit.
The first 3 band on a resistor indicate the value of that resistor.
To determine the value of Stabilizing resistor Rs = Vs/Is = If(Rct +2Rl)/Is Where, Rs = resistance value of the stabilizing resistor Vs = voltage at which the relay will operate Is = current flowing through the stabilizing resitor and the relay If = maximum secondary fault current magnitude Rct = internal resistance of the current transformer Rl = resistance of attached wire leads

what does the term stabilizing fin mean
That is the definition of stabilizing selection.
Stabilizing selection
When natural selection favors the intermediate version of a characteristic, it is referred to as stabilizing selection. It is the opposite of disruptive selection.
how it can be both a stabilizing force and a source of conflict in societies.

Examples of hydrogen peroxide stabilizing agents are acetanilide, organphosphonates, phenol, etc.
Stabilizing selection results in less genetic diversity in a population.
