Performance Analysis and Protection of Submersible Motor for Unbalance Condition in Dewatering

This study discusses the safety of submersible motors in dewatering under current unbalanced conditions. Submersible motors are commonly employed in artificial lifting systems used in dewatering conditions. The submersible motor is vulnerable to hazards that might cause injury during the current imbalance state in dewatering. The researcher offers a basic protection mechanism that he has devised and a performance study of the submersible motor. Work on dewatering difficulties was finished in this study, and the suggested solution sought to safeguard the submersible motor. The protective strategy is effectively realized by utilizing three temperature sensors based on submersible motor coils by transmitting the signal to the microcontroller, which identifies the defective phases and sends the tripping signal to the AC drives (inverter) and sensors (water), submersible motor probe with ceramic measuring cell, and submersible motor inverter. In addition, the simulation and experimental results for various operating locations are shown in this study. The outcomes are in line with the goals that were set. This study provides guidelines for high-performance submersible motors in wells due to groundwater conditions. These guidelines are based on several failures discovered during an examination. Furthermore, this report suggests many techniques for preventing these failures. These suggestions are based on the investigation of numerous submersible motor pumps from various manufacturers in various wells in Egypt with short-term operations induced by various situations encountered while working on the site.
