Abstract
Objectives:
1. Reduce the distortions due to electrical harmonics.
2. Improvement of the performance of the electric power system
3. Design simulation cases of harmonics and
propose ways to overcome them.
4. Access to the original form for the waves of the voltage and current.
5. Enhance the skills of the electrical power quality for electrical technology students in the faculty of Industrial Education.
6. Development a suggested training program to raise the quality of the skill performance in electric power system for electrical technology students at the Faculty of Industrial Education - Helwan University.
CONCLUSIONS:
Arc furnace loads have deleterious effects on power systems which produce harmonics these harmonics are odd and even harmonics it’s found that the THD for current and voltage exceed the fundamental. Using of single tuned filter can element harmonics, so2hd, 3rd, 4th and 5th single tuned filter are designed and connected at the pcc. After connecting these filter, the THD is improved and become within limit.
