Name of Innovative Method Adopted: Role Play
Name of Course: Electrical Drives
Topic Covered: Workshop on Power Analyzer for Harmonic Analysis
Description: Role Play
Goals for Adopting Method: To make students clearly understand the concepts of an electric drive, incorporation of power electronics, utilization of power analyzer for harmonic analysis and THD measurement.
Description of Methodology:
The basic concept of an electric drive with its block diagram was explained thoroughly through the board work with detailed understanding of each block. The experiment was conducted by running an induction motor without the involvement of power electronics and the measurement of harmonics was executed with the help of power analyzer. In the next stage, an induction motor based drive was run, and measured harmonics were shown through the power analyzer which clearly have shown significant data in the same. The analysis for the appearance of harmonics with drive and without drive has been done and explained to the students.
Significance of Method: The students will be able to correlate with the practical aspects of the machine running independently and as a part of the drive and will be able to discriminate against the presence of harmonics and their THD values.

Topic Covered: Hands on Workshop on PVSYST Software for Solar PV Design and Analysis
Description: Role Play
Goals for Adopting Method: To make students clearly understand the concepts of an Solar Power Plant design as per the geographical aspects of the land and technological parameters related to the Solar PV system, battery and inverter.
Description of Methodology:
The students were given the brief explanation about the PV Syst Software and its operation. The students have been explained about various operating parameters for the design of the Solar Power plant and also given insight into the selection of the values of those parameters. The students afterwards designed their own Solar power plant with a different geographical location and verified the output.
Significance of Method: The students learnt the selection of the parameters related to solar panels, battery, inverters and primary design and analysis.

Topic Covered: Learning Through Field Visit “Transformer Oil Filtration Process”
Description: Role Play
Goals for Adopting Method: To make students clearly understand the concepts of the working principle and operation of transformer and the impact of Oil filtration and the process of it.
Description of Methodology:
The Experts & Technician from the industry visited VVP Engineering College Campus and as a part of maintenance of transformer they checked and demonstrated the filtration process. They started with the way to check the moisture effect on the transformer by checking the color of silica gel visual appearance. (silica gel used in transformer is blue it becomes pink from the original color blue due to moisture effect).Initially they took a bit of transformer oil and checked the BDV (Breakdown Voltage) it was very less around20kV.They started the filtration process by pouring and filling the empty oil tank. They for almost 1 hour they did filtration process in four stages and explained the same to all the students. At regular intervals they kept on checking the BDV and the temperature level.
Significance of Method: The students learnt about the oil filtration process of the three phase transformer and testing of breakdown voltage with its importance.

Topic Covered: Learning Through Field Visit “Distribution of Electrical Power and its Wiring.
Description: Role Play
Goal for Adopting Method: To make students clearly understand the concepts of distribution of electrical power in the premises through the wiring and utilization of electrical equipment.
Description of Methodology: The students have been explained about the various stages of electricity starting from generation, transmission, distribution and its end towards utilization. The students were then, taken to the electrical maintenance room which comprises of panels, switches related to the connections of the supply source which is coming from the PGVCL and the solar power plant installed on the institute premises followed by diesel engine based generator. The students were then exposed to the three phase transformer operation, its working principle, construction etc. and then the stepping down of voltage from 11kV to 415 volts. The wiring is then explained related to the working of the appliances at distribution levels.
Significance of Method: The students learnt about the oil filtration process of the three phase transformer and testing of breakdown voltage with its importance.
