As part of the ongoing efforts to ensure the sustainability and operational efficiency of laboratory equipment for student service, the Maintenance Committee in the Department of Electrical Engineering Technologies completed technical rehabilitation works for the Discrete Component Trainer in Laboratory (305) on Wednesday, April 1, 2026, following a total system failure caused by an electrical malfunction. The committee, represented by Teaching Assistants Ali Naji Radhi and Haider Karrar Hussein, conducted a comprehensive technical inspection. The diagnostic process identified a fault within the Power Supply unit, leading to a voltage interruption. Additionally, the fuse was found to be blown due to a sudden current surge, accompanied by degradation in internal connection points and DC output terminals. Upon identifying the malfunctions, the engineering team executed a series of technical maintenance procedures, including: Replacement of Damaged Components: Installing a new fuse compliant with the device's original technical specifications. Technical Processing: Re-soldering damaged circuit paths, reinforcing connection points, and regulating the power supply circuit to ensure current stability. Testing and Calibration: Verifying AC/DC voltage outputs and ensuring the accuracy and responsiveness of measurement indicators. The maintenance work concluded with a successful experimental operation of the device, demonstrating full operational readiness and performance efficiency. This initiative aligns with the department's strategy to modernize laboratories and provide optimal practical tools that enable students to simulate theoretical concepts with the highest standards of precision.
