SS316 has higher corrosion resistance and strength compared to SS304.
SS316 contains molybdenum which enhances its corrosion resistance, while SS304 does not.
SS316 is more suitable for use in harsh environments like marine applications, while SS304 is more commonly used in indoor settings.
SS316 has higher tensile strength and creep strength than SS304.
SS316L has lower carbon content than SS316, making it more corrosion resistant and suitable for welding applications.
SS316L has lower carbon content (0.03% max) compared to SS316 (0.08% max)
SS316L is more corrosion resistant due to the lower carbon content
SS316L is commonly used in welding applications where post-weld annealing is not possible
SS316 is more commonly used in applications where higher strength is required

Testing for oil leakage in transformers involves visual inspection, oil analysis, and pressure testing.
Visual inspection of the transformer for any signs of oil leakage
Oil analysis to check for any abnormal levels of dissolved gases or contaminants
Pressure testing to check for any leaks in the transformer's oil-filled compartments
Use of ultrasonic testing to detect any leaks in the transformer's tank
Regular maintenance
I will conduct a thorough testing and inspection process to identify any errors in the Feeder.
Perform visual inspection of the Feeder
Conduct electrical testing to ensure proper functioning
Check for any loose connections or damaged components
Compare the Feeder's performance to the expected results
Review any error logs or system alerts
Consult with colleagues or experts for additional input
