Why Use Our Services?

With today’s state-of-the-art technology, the effectiveness of fault recovery studies must be enhanced to include reacceleration of high torque loads. The cornerstone is the utilization of voltage sensitive load models.

Since the 1960s, electric utilities have used computer-based transient stability models to determine if the electric power grid would stabilize after faults are cleared. These studies provide a reasonable assessment of the ability of large, central generating stations to remain synchronized to the power grid. However, these studies do not account for high torque loads that stall when voltage dips below 70% for more than 50 milliseconds.


Innovations in technology must be matched by innovations in the models used to assess fault recovery effectiveness. Contact us to learn more.

Description of Services

Prescient’s team works with your staff to develop enhanced models that accurately represent the reacceleration of connected load when three phase faults are cleared.

Prescient analyzes customer loads during low load and peak load conditions and directs the refinement of load models to account for voltage dips during three phase faults on nearby transmission facilities.

We then direct the development of enhanced models that include reacceleration of high torque loads that were affected by voltage dips.
