RESEARCHING AND DESIGNING MULTI-FUNCTIONAL VOLTAGE AND CURRENT MONITORING DEVICE

Abstract

This paper presents the research and design of a multi-functional current and voltage monitoring device. With this device, the current and voltage from the power supply to the loads will be monitored and checked continuously in real time. When problems occur, mainly errors due to power quality are not guaranteed such as phase loss, high voltage, low voltage, high frequency, low frequency,... the device will broadcast alarm signals to inform the users. This ensures that devices will be working with high power quality, minimize the effects that poor power quality brings as devices will work with low efficiency, longevity of equipment reduced,...
