Throughout my professional journey, I have gained hands-on experience utilizing paddle flow switches, turbine flow sensors, and differential pressure sensors.
o While working as an electrical maintenance engineer in Egypt Cables, I came across a recurring issue of voltage unbalance. Interestingly, this problem was causing the rectifier of AC drives to blow specifically during the night shift. To resolve this peculiar situation, I embarked on a journey to trace the problem back to its root cause, which turned out the root cause was an unequal distribution of lighting loads among the phases. This experience taught me the significant detrimental effects that voltage imbalance can have on industrial processes.
o I have successfully resolved numerous concerns pertaining to pneumatic controls. I possess expertise in various types of valves such as the Two-way Two-Position Valve, Three-Way Two-Position Valve, Four-Way Two-Position Valve, and Four-Way Three-Position Valve.
o Control valves that depend on air pressure for functioning and can be adjusted to regulate the flow from fully closed to fully open are widely used in the food industry. I have practical experience working on such valves at a pasta factory during my part-time employment. I am well-acquainted with motorized operated valves (MOV), as well as the calibration of closing torque sensors and fully open limit sensors.
o Throughout my day at Egypt Cables, I spend big portion of my time repairing extruders. This hands-on work has provided me with a vast amount of expertise in dealing with temperature sensors, specifically thermocouples, resistance temperature detectors (RTDs), and temperature transmitters.
o I have successfully calibrated numerous temperature transmitters that utilize a resistance temperature detector (RTD) as their transducer. To accurately simulate the transducer, I employed a precise decade resistance box. Throughout the calibration process, I consistently adhered to the manufacturer's recommended guidelines, which inevitably resulted in flawless calibrations.
o I have extensive knowledge regarding the functioning and application of resistance temperature detectors (RTDs) that employ two, three, and four wire configurations.
o I possess ample expertise in fine-tuning PID control. It involves a comprehensive and iterative process, where trial and error, combined with experience, and intuition play a significant role in achieving successful tuning.
o I derive great pleasure from programming, as it truly captivates my interest. that makes implementing relay logic control particularly effortless and straightforward.
o Working with motor control circuits is my area of expertise. My primary responsibility entails diagnosing and repairing reduced voltage starters, such as star-delta starters, autotransformer starters, and part-winding starters. It is my regular duty to ensure these circuits are functioning optimally.
o I possess the capability to perform the tasks of grouping, phasing and polarity check of an unmarked 6-wire induction motor, a dual voltage motor with a star connection configuration consisting of 9 leads, as well as a dual voltage motor with a delta connection configuration and with 9 leads.
o I possess extensive knowledge about AC drives. I have programmed AC drives to function using both V/f Control and Vector Control techniques. While employing Vector Control, I consistently prioritize the utilization of encoder feedback to ensure optimum performance, even at extremely low frequencies ranging from 0 to 1 Hz. When tuning the vector control settings, I always make sure to connect the mechanical load and choose tuning with load connected to achieve the most favorable outcomes.
o I encountered numerous challenges with capacitor correction panels in the facility where I was employed. The facility experienced a significant issue with harmonics, resulting in a high level of total harmonic distortion. This, in turn, led to frequent failures of the capacitors. Through this experience, I gained valuable insight into the risks posed by harmonics and discovered various methods to address and reduce them, such as implementing line reactors with 3 and 5 percent impedance.
