Andhra Pradesh: Now a switch to monitor electrical load | Visakhapatnam News

VISAKHAPATNAM: Researchers at the Andhra Pradesh National Institute of Technology have developed an ‘advanced computing stack’ to monitor and control electrical loads through intelligent powerline communications.
This device is an Internet of Things (IoT) based electrical switch designed to check the consumption of electrical appliances. NITAndhra Pradesh plans to commercialize this patented product by establishing a start-up to grow it as an individual entity.
The device is unique due to its hybrid approach to power line communication and Wi-Fi and has issued an Indian patent. It was developed by Dr. Sri Phani Krishna Karri, Assistant Professor, Department of Electrical Engineering, with LN Sastry Varanasi, Researcher.
Dr. Phani Krishna said the system solves energy mismanagement on the consumer side, which is a problem for both the utility company and the customer. “This product is intended to optimally manage electrical power and monitor device-level health using existing electrical infrastructure. It will also reduce recurring maintenance costs and electricity bill,” he said.
The system consists of two modules, namely “master” and “slave”. The master device communicates with a mobile device via a wireless medium. Slave devices are directly connected to electrical devices, which detect the voltage, current, power and power factor of each device. The detected information is communicated to the master device via power line communication.
The system uses the existing electrical infrastructure as a means of communication inside the house or organization that records the consumption of each electrical device and makes it available to the user for remote monitoring and control through a mobile device.
LN Sastry said they plan to market as a start-up. “However, for a broader scope, we are considering licensing the technology to develop various products,” he added. NIT-AP Director Prof. CSP Rao appreciated the work done by the faculty member and the researcher and encouraged the staff for such interdisciplinary collaborative research work in emerging applications.
