Abstract

Voltage sags and swells are the most prevalent kind of disruptions in the electric power grid. Most of the time, it is caused by a short circuit, a sudden shift in load, a loose connection, or the start of the heater or engine. Most electronic equipment is susceptible to voltage sags and swells, which can result in malfunctioning electrical components or an abrupt reboot of the system, which can then cause the equipment to cease functioning completely. When voltage sags or surges occur sporadically, it is extremely difficult to pinpoint the source of the sags or swells and determine their cause. A device that can detect voltage sags or swell for single phase 240V power distribution system is being created using an Arduino-based circuit that is connected to the internet in order to assist technicians or engineers in identifying the source of voltage sags or swell. A cloud platform will retain the data from the device, which will record when a sag or swell is observed, as well as the time and duration of the occurrence. In addition, a web-based interface will be built to display the data to the user.
