Harmonic Filter and Transient Voltage Excursion Ride-Through

This project consists of two parts. Part 1: Harmonic Filter A 480 volt motor control center supplies small motors totaling 550 horsepower. The total load on the motor control center is 460 kW and 300 kvar. Because of variable frequency drives, a substantial harmonic content exists in the current, as shown by a power quality analyzer Part 2: Transient Voltage Excursion Ride-Through An industrial facility is experiencing transient voltage excursions (outside the ITI envelope) which are causing critical manufacturing equipment to shut down. A total of 75 kVA of load is being affected by the least serious of the voltage excursions, and a total of 175 kVA of load is affected by the most serious excursions.
