Design starting capasitor motor submersible pump with Zelio SR2B121FU

Author(s): Adhi Kusmantoro, Agus Nuwolo
Abstract: In the single phase induction motor cannot start itself. To be able to start their own, the motor requires tools that are used at the start or during the motor is running. For this type of submersible pump motor capacitor is outside the motor, because the motor submersible pump immersed in water. At the present time in Indonesia starting submersible pumps have faced problems, especially relay on the capacitor is not able to work optimally, so do some research to design a submersible pump starting to improve.This research is a case study that aims to improve the performance of a single-phase submersible pump.Submersible pump motor works with DOL method. This method produces a high starting current is 27 A in a time of 0.25 seconds. Flow starting on coils 10 A and just walk around 0.25 seconds. After 0.25 seconds coils are disconnected from the main circuit so no current flows. Working voltage on the capacitor 110 V and is only used for starting in a time of 0.25 seconds. Graph speed submersible pump motor produces 2950 rpm speed at 2.5 seconds.System starting capacitor single-phase submersible pump more effectively by using Zelio SR2B121FU. Starting of submersible pumps with DOL method has a starting current of 27 A and full load current 10 A. Penegendalian submersible pump motor single phase using Zelio SR2B121FU provide security in operating it. The time needed to disconnect the capacitor from the coils using RSL1PVBU relay by 0.25 seconds.
