- 20 What is countertorque a measure of? PRACTICAL APPLICATIONS ou are working as an electrician in a large steel manufacturing plant, and Y in the of doing preventive maintenance on a large DC you are generator. You have megged both the series and shunt field windings and found that each has over 10 M2 to ground. Your ohmmeter, however, indicates a resistance of 1.5 2 across terminals S, and S,. The ohmmeter indicates a resistance of 225 N between terminals F, and F2. Are these readings normal for this type machine, or is there a likely problem? Explain your answer. processReconsider Problem 3.29. If Va,VbandVc are a negative-sequence set, how would the voltage and current relationships change?

- Cutting forces should be kept constant during machining operations to prevent changesin spindle speeds or work position. Such changes would deteriorate the accuracy of thework’s dimensions. A control system is proposed to control the cutting force. The plantis difficult to model, since the factors that affect cutting force are time varying and noteasily predicted. However, assuming the simplified force control model shown inFigure (ii) Determine the range K to keep the system stable using the Routh-Hurwitzcriterion.SUBJECT: Elements of Electrical Machines DesignINSTRUCTIONS: - Please write clearly and understandable way. - Write all the corresponding Given with their corresponding symbols and units. - Draw/Illustrate the diagram/circuit or drawings that is related to the problem, IF POSSIBLE, which is HIGHLY REQUIRED. - Solve in step-by-step, no shortcut - Underline twice the Final Answer.PROBLEM: When does the polarity of a transformer become significant?Please help with this problem and explain the steps to solve
