    The use of non-linear power loads causes power system distortion or harmonic problems. When that problem occurs, it must be resolved in time. Therefore, this document presents an online power quality measurement system that can quickly notify events and information. Fast data acquisition results in the quick analysis as well. Finally, the electrical system will be solved by installing a hybrid filter that is suitable for that problem.

    The ac drives which operate at a poor power factor decreases motor speed and injected large harmonic current and subra-harmonics into the supply network. The effects of harmonic and subra-harmonic that are injected into the network include overheating of transformers and motor and other instrumentation that were not designed with an insensitivity to harmonic in the supply. Thus, some form of harmonic and subra-harmonic mitigation is required. The PQube3 compact instrument is simply the best power monitor and real-time sensor and it records harmonic and supra-harmonics of AC drive for dry-milling system. To reduce the harmonic current and subra-harmonic injected in the network. The Hybrid Power Filter System(HPFs) are chosen because they can solve this problem with the least cost and the same effect as active filter. The results show that the association of HPFs is a very good solution for harmonic and subra-harmonic problems.
