LEARNING OUTCOMES
After studying Installation, Maintenance and Repair of Electrical Equipment (IMREE) subject, students will able to:
- Erect/install various electrical equipment as per IE Rules Act by adopting allsafety measures.
- Prepare specifications for different items required for transmission lines.
- Design and excavation of cable trenches.
- Lay underground cables
- Test cables and their termination.
- Check HT/LT circuit breakers, transformers and related equipment in a substation
- Carry out earthing, make earth pits and measure earth resistance values.
- Find fault in a transmission/distribution system.
- Carry out preventive maintenance to minimize breakdowns.
INSTRUCTIONAL STRATEGY
This subject needs theoretical and practical inputs. Demonstration at actual site may be arranged for conceptual understanding. The subject teacher should plan in advance about the visits to the actual sites and establish liaison with the appropriate authorities/ persons with the help of HOD and
Principal of the institution. The students be taken to actual workplace and explain various test procedures.
MEANS OF ASSESSMENT
− Assignments and quiz/class tests, mid-term and end-term written tests, model/prototype making.
− Actual laboratory and practical work, model/prototype making, assembly and disassembly exercises and viva-voce.
LIST OF PRACTICALS
- Testing of Insulation Resistance of PVC in PVC wire, measurement of winding resistance of
a motor. - Wiring of tube light connection with starter and choke.
- Oil testing of a transformer and note its breakdown value.
- Make a alarm circuit.
- Make ON/OFF control circuit to run an electric induction motor (Single Phase)
- Make a circuit to run a ceiling fan.
