Integrated Power Monitoring and Control System
International Journal of Emerging Engineering Research and Technology · 2017
This paper presents the design and construction of an Integrated Power Monitoring and Control System which automatically changes over from a low / dead phase to a best / live phase for continued supply of power to load, building or apartment with preset configuration such as: 3 phase supply in (with 1 phase output to load/equipment), inbuilt phase and voltage monitoring sensors, automatic dead phase detection, automatic load transfer to live/active phase, load isolation switch incorporated (The product can serve as a load isolator, totally cutting off mains power from load), user friendly phase selector switches (to manually select any phase of your choice, this is an 'Automatic mode' over-ride function).It can provide real-time information about the following electrical parameter: Voltage, Current, Power Factor, Active Power, Apparent Power, Energy and Frequency.The system is also expected to be able to perform the function of electrical protective devices such as overvoltage, under-voltage, over-current, abnormal frequency and excessive power consumption prevention devices.This device uses only electronic components for the control such that it can be used with smaller generators which do not have this automatic feature on them.
