i introduction
I. Introduction
  • Why is the project being done?
  • -To correct short voltage sags (a few seconds) to maintain a stable voltage to critical loads.
  • Why is this important?
  • -The shutdown of critical loads due to short voltage sags can be costly.
ii primary objective
II. Primary Objective
