A more thorough explanation:

Definition: A perturbator is someone or something that causes disturbance or disruption.

Example 1: The loud construction work outside my window is a perturbator to my concentration while studying.

Example 2: The sudden power outage was a perturbator to the smooth running of the factory.

These examples illustrate how a perturbator can cause disturbance or disruption to a person or a system. In example 1, the noise from the construction work is causing a disturbance to the person's ability to concentrate. In example 2, the power outage is disrupting the smooth running of the factory.
