PENGARUH LETAK KAPASITOR TERHADAP PERBAIKAN FAKTOR DAYA PADA INSTALASI MOTOR LISTRIK

The addition of capacitors to the motor load acts as the reactive power supply required by the motor so that themotor load no longer draws much of the reactive power from the system. The reactive power of the unused powersystem into energy is only required to generate magnetic flux on the inductive load. However, this reactive powerremains a burden for power generation which, when the value is large, causes the system power factor to decrease. Theaddition of capacitors as reactive power compensators to their applications, most of them are placed close to loads thatrequire reactive power compensation. In this research, experimental research has been done by placing the capacitorcompensator in different position to see the condition of the system response to the condition of the motor installation.Test results indicate the effect of capacitor’s positioning as an improvement of the power factors for a powerinstallation. Power factor improvements will be optimal when capacitors are placed for individual compensationpositions compared to global compensation and group compensation positions
