Harmonic pollution filtering: case study of a university campus

This paper provides a study of the benefits and improvements in electrical power quality obtained by filtering harmonic pollution. A continuous 7-day measurement by a network analyzer at the secondary level of a higher education institution's transformer proved the existence of important harmonic pollution. We proposed to attenuate these harmonics by installing passive filters at the general circuit breaker. The simulations were carried out with Matlab/Simulink software, based on a set of data measured by the network analyzer. This harmonic pollution-filtering project will improve the quality of power and make significant energy savings.
