During which phase of DMAIC will you identify the root cause of the problem?
In the DMAIC (Define, Measure, Analyze, Improve, Control) standard improvement model, the most commonly used tool to identify the root cause(s) of a problem is the Fishbone Diagram, also known as the Ishikawa Diagram. This visual tool helps teams categorize potential causes of problems into major categories, such as people, processes, materials, and equipment, facilitating a structured analysis. Other tools, like the 5 Whys and Pareto Analysis, can also complement this process, but the Fishbone Diagram is particularly effective for comprehensive root cause analysis.
In a 3 phase, star connected system, the phase to phase voltage and phase to neutral voltage is calculated using root 3. That is, phase to phase voltage is root 3 times phase to neutral voltage. Also to calculate three phase power the voltage and current is multiplied by root 3 to obtain 3 phase power with unity power factor.AnswerIf you vectorially-add two quantities that are displaced from each other by 120 degrees, then the resulting quantity will be 1.732 (i.e. the square-root of 3) longer. Try it for yourself.So, for a wye (star) connected system, the phasor (vector) sum of two phase voltages will result in a line voltage that is 1.732 times larger than a phase voltage. For a balanced wye (star) connected load, the phasor sum of two phase voltages will result in a line current that is 1.732 larger than a phase current.
The formula to use is, phase voltage /1.73 = phase to neutral (ground) voltage.CommentThere is no such thing as a 'phase to phase', or 'phase to neutral' voltage. The correct terms are 'line to line' and 'line to neutral'. So the above answer should read: line voltage/1.73= line to neutral voltage = phase voltage.
Phase voltage is equal to the line to line voltage divided by root 3 or 1.732. So 440 L-L/1.732 = 254V. Your phase voltage is 254V.

During which phase of DMAIC will you identify the root cause of the problem?
The root causes of the problem are identified during the Analyze phase of DMAIC. In this phase, data collected during the Measure phase is examined to uncover the underlying factors contributing to the problem. Techniques such as root cause analysis, process mapping, and statistical analysis are commonly used to ensure a thorough understanding of the issues at hand. This step is crucial for developing effective solutions in the subsequent Improve phase.
