SAFETY is of extreme importance in the Electrical Engineering Laboratories. rejinpaul.com have taken efforts in providing the Regulation 2017 EEE Laboratory Manuals in PDF format. 1 open circuit & short circuit test on a single phase transformer . ELECTRICAL MACHINE LAB. 3. 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. LABORATORY PRACTICE SAFETY RULES 1. 3 scott connection of transformers. 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. Fig – 1.2 SC Test on Single Phase Transformer 1.5 PROCEDURE: :O. OBJECTIVE : To study the speed control of induction motor by varying supply frequency (V/f control). Sum up the Ammeter readings (I1 and I2) , that should be equal to total current (I). Make the connections as per the circuit diagram. Upgrade to Prime and access all answers at a price as low as Rs.49 per month. 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. 6. 2. THEORY : The air-gap induced emf in an ac machine is given by High blood pressure or hypertension affects more people than one can possibly think. 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. 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 2. 3. 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 DEPARTMENT OF ELECTRICAL & ELECTRONICS ENGINEERING 13 14. Connect the circuit diagram as shown in Figure 2. Total Page 52 . The transformer works on the principle of electromagnetic induction between two windings placed on a common magnetic circuit.
