Sum up the Ammeter readings (I1 and I2) , that should be equal to total current (I). 2 sumpners test. Upgrade to Prime and access all answers at a price as low as Rs.49 per month. Note the readings of Ammeters. ELECTRICAL MACHINE LAB. 5. 2. 1. 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 Apply rated voltage with the help of autotransformer across LV winding, with the HV winding as open circuited. THEORY : The air-gap induced emf in an ac machine is given by Apply the voltage (say 5v) and note the Ammeter readings. C TEST 1. A.C. Electrical Machines Lab GRIET/E.E.E. Precautions: 1. 3. 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. 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. 2. 1 open circuit & short circuit test on a single phase transformer . lab manual experiment names. LABORATORY PRACTICE SAFETY RULES 1. 3. 3. 2. Note down the readings of voltmeter (V), Ammeter (I o) and wattmeter (P o). Uploaded 3 years ago . Make the connections as per the circuit diagram. 6. OBJECTIVE : To study the speed control of induction motor by varying supply frequency (V/f control). 4. MANUAL EE 591 Page | 6 EXPERIMENT NO: EM – II/2 TITLE SPEED CONTROL OF THREE PHASE SQUIRREL CAGE INDUCTION MOTOR BY VOLTAGE CONTROL AND FREQUENCY CONTROL METHOD. Electricity NEVER EXECUSES careless persons. (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. 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. (Electricity is a good servant but a bad master). Connect the circuit diagram as shown in Figure 2. The transformer works on the principle of electromagnetic induction between two windings placed on a common magnetic circuit. Gradually increase the supply voltage in steps. 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 LABORATORY MANUAL ON ELECTRICAL MACHINES - II LABORATORY 2018 – 2019 III B. SAFETY is of extreme importance in the Electrical Engineering Laboratories. Total Page 52 . The readings of the total power input are Wo, Io and voltage V are plotted. 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. High blood pressure or hypertension affects more people than one can possibly think. 2. All the connections should be tight and clean. Fig – 1.2 SC Test on Single Phase Transformer 1.5 PROCEDURE: :O.
