The 7QC tools of quality are essential techniques used in quality control to identify and solve problems.

• Check sheets: Used to collect and organize data, such as defect counts

• Pareto charts: Helps prioritize issues by showing the most significant factors

• Cause-and-effect diagrams: Identifies root causes of problems

• Histograms: Displays data distribution

• Scatter diagrams: Shows relationship between two variables

• Control char...read more

I worked at XYZ Company as a Quality Engineer for 3 years.

• Implemented quality control processes to improve product reliability

• Conducted root cause analysis for non-conformances

• Collaborated with cross-functional teams to address quality issues

A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Consists of two coils of wire, known as primary and secondary coils

• Primary coil receives electrical energy and creates a magnetic field

• Magnetic field induces a voltage in the secondary coil, transferring energy

• Used in power distribution, voltage regulation, and isolation

• Examples include step-up tran...read more

Protection of generator involves implementing various measures to prevent damage during abnormal operating conditions.

• Implementing overcurrent protection to prevent damage from excessive current flow

• Installing differential protection to detect internal faults

• Using reverse power protection to prevent generator from acting as a motor

• Applying overvoltage and undervoltage protection to safeguard against voltage fluctuation...read more

0.02 of least count refers to the smallest measurement that can be made with a measuring instrument.

• Least count is the smallest measurement that can be made with a measuring instrument.

• It is determined by dividing the smallest measurement that can be read on the instrument by the number of divisions on the scale.

• For example, if a ruler has 100 divisions and the smallest measurement that can be read is 1 mm, then the le...read more

To measure micrometre reading, use a micrometre screw gauge and take the reading from the scale and thimble.

• Clean the micrometre screw gauge before use

• Place the object to be measured between the anvil and spindle

• Turn the thimble until the object is firmly held

• Read the scale and thimble to get the micrometre reading

• Take multiple readings and calculate the average for accuracy

Fishbone diagram is a visual tool used to identify the possible causes of a problem.

• Also known as Ishikawa diagram or cause-and-effect diagram

• Used in quality control to identify root causes of defects

• Categories include people, process, equipment, materials, environment, and management

• Example: A fishbone diagram can be used to identify the possible causes of delays in a manufacturing process
