| Abstract | Control systems of switchable transformers play a prominent role in achieving precise timings for switching actions and providing monitoring and protection for the transformers. Since the first energy efficient distribution switchable transformer was designed and built, several designs of control system have been introduced. This paper presents a further development of the control system design which is intended to be embedded in a 3-phase 10 kVA energy efficient switchable distribution transformer. The overall new idea in this design is to implement a modular approach and CAN (Controller Area Network) bus so that multiple jobs can be handled in parallel and a better performance of a control system can be achieved. An AVR microcontroller from Atmel with a built-in CAN controller is used to handle controlling, processing and communication in each module. A physical connection called CAN bus is implemented to achieve reliable communication for up to 1Mbit/s between the modules. Furthermore, a simple protocol has been developed and tested using several microcontroller development boards. This protocol handles transfer of data which are mostly digital values as representation of physical parameters from voltage transformers, current transducers and temperature sensors. The overall system has been tested by applying multiple complex jobs that should be handled by the system, such as reading sensors, processing data, timing controls, remote monitoring and protection. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
