Upgrade to Prime and access all answers at a price as low as Rs.49 per month. LABORATORY PRACTICE SAFETY RULES 1. All the connections should be tight and clean. 2. Tech I Semester (JNTUA-R15) Mr. K. Raju,Assistant Professor CHADALAWADA RAMANAMMA ENGINEERING COLLEGE (AUTONOMOUS) Chadalawada Nagar, Renigunta Road, Tirupati – 517 506 Department of Electrical and Electronics Engineering 5. ELECTRICAL MACHINE LAB. If we subtract loss corresponding to OA from Wo, then we get the no-load electrical and magnetic losses in the machine, because the no-load input Wo to the motor consists of (i) small stator Cu loss 3I o ² R 1 (ii) Stator core loss W c = 3 G o V c B.E Electrical and Electronics Engineering Lab Manual Anna University Regulation 2017 Students of Regulation 2017 can download the EEE Lab Manuals from 1st Semester to 8th Semester in this page. lab manual experiment names. > Electric Machinery by A.

Apply the voltage (say 5v) and note the Ammeter readings. 3. Sum up the Ammeter readings (I1 and I2) , that should be equal to total current (I). (Electricity is a good servant but a bad master). The readings of the total power input are Wo, Io and voltage V are plotted. 1. (in Watts) = Wattmeter Reading*M.F Short circuit current=Ammeter reading= I sc Voltmeter Reading = V sc Copper loss = Wattmeter Reading =W sc Calculate the values of R 01, X 01, Z 01. 3 scott connection of transformers. Electricity NEVER EXECUSES careless persons. Gradually increase the supply voltage in steps. 7. Apply rated voltage with the help of autotransformer across LV winding, with the HV winding as open circuited. USHA RAMA COLLEGE OF ENGINEERING & TECHNOLOGY EM-II LAB MANUAL Prepared by Mr. J Satish Babu & Mr. A. LokeshDEPARTMENT OF ELECTRICAL & ELECTRONICS ENGINEERING 1 ... Tabulate the readings as shown. Switch ON the supply to RPS. 2. As more and more doctors recommend people to use home blood pressure monitors to keep a regular check on their blood pressure readings at home, there is a common debate regarding which type of blood pressure testing machines are better – automated or manual blood pressure readings. Total Page 52 . Electrical machines 2 lab manual 1. 6. 2. The transformer works on the principle of electromagnetic induction between two windings placed on a common magnetic circuit. OBJECTIVE : To study the speed control of induction motor by varying supply frequency (V/f control). Note down the readings of voltmeter (V), Ammeter (I o) and wattmeter (P o). 2 sumpners test. DEPARTMENT OF ELECTRICAL & ELECTRONICS ENGINEERING 13 14. High blood pressure or hypertension affects more people than one can possibly think. A.C. Electrical Machines Lab GRIET/E.E.E. Precautions: 1. 4. C TEST 1. 7 Theory: A transformer is a static device which transfers the electrical energy from one circuit to another circuit without any change in the frequency. 3. LABORATORY MANUAL ON ELECTRICAL MACHINES - II LABORATORY 2018 – 2019 III B. 1 open circuit & short circuit test on a single phase transformer . Connect the circuit diagram as shown in Figure 2. Make the connections as per the circuit diagram. THEORY : The air-gap induced emf in an ac machine is given by rejinpaul.com have taken efforts in providing the Regulation 2017 EEE Laboratory Manuals in PDF format. 2.
