    The proliferation of servo drives (SD) in the industry has led to serious concerns about harmonic resonance and power quality in electrical distribution systems. This paper reported the resonance conditions of electrical systems with motor control using a small servo drive for use in CNC machines. When a large number of servo drives are combined, it results in harmonic resonance occur in the system. Resulting in the destruction of electrical equipment such as power supply, computer, CNC, or servo drive close to each other, etc. The cost of purchasing the above electrical equipment to replace the damaged ones in each month is very high. A simple passive power filter system (PPFs) design is recommended to reduced harmonic resonance. PPFs are applied to the system and the actual installation which is satisfactory and can greatly reduce the damage of electrical equipment. Finally, the factories can save money each month.

    This paper is a preliminary basis in the design, planning, and implementation of hybrid power filter systems (HPFs) for application in grid-connected solar rooftop at industrial plants beginning the planning and designing of a 260 kWp solar rooftop according to the factory roof size. Calculate total returns by using the PV system design software program to find the total kWh received per year. As the power system in this factory has a load that is sensitive to power quality and harmonics, it is necessary to design a harmonic protection system by choosing the HPFs to reduced and control the harmonics. Noise filters should be used to prevent high-frequency signals from entering the electrical system. In addition, lightning protection devices are also designed by using the bus bar to connect the system to the ground. All actions have been carried out in accordance with the designed plan and able to perform as intended.
