    Electricity theft is one of the problems - encountered by the utilities - that leads to losses of revenue. Manual monitoring of the consumers’ activities which shows the energy data consumed on the conventional grid has largely contributed to electricity theft on the grid. Significantly, the energy meter deployed to monitor the load cannot store and transmit energy data in real-time. This has made electricity theft on the grid unnoticed. This paper presents the development of a monitoring scheme for an electronic meter on the conventional grid with the capability to monitor, store and transmit consumers’ energy data to the cloud. It consists of two units: the indoor and the outdoor unit. Energy data is transferred wirelessly between the units via the Wi-Fi modules. The outdoor unit compares the data and transfers the outcome to the ThinkSpeak cloud server. The transferred energy data can be accessed in real-time from the cloud or downloaded in comma-separated values format for further use. In order to verify the functionality of the proposed scheme, two scenarios of electricity theft - partial bypassing and full bypassing - are carried out. The obtained results show that the scheme can detect the theft and log the data to the cloud successfully.

    Development Of A Cloud-Based Condition Monitoring Scheme For Distribution Transformer Protection
    (Universitas Sriwijaya, Indralaya, Indonesia, 2023-02) Abdullateef, Ayodele Isqeel; Issa, Abdulkabir Olatunji; Sulaiman, Abdullah; Salami, Momoh Jimoh Eyiomika; Otuoze, Abdulrahaman
    Distribution transformers are a necessity to ensure a reliable power supply to consumers and their inability to function properly or even breakdown should be avoided due to the high cost of replacing them. Distribution transformers are large in numbers and randomly distributed in cities and there is a need to accurately monitor their daily/hourly performance. To achieve this, real-time monitoring of the transformer’s health status is proposed rather than the use of the traditional approach involving physical inspection and testing which is slow, tedious and time-consuming. This paper presents a cloud-based monitoring scheme applied to a prototype distribution transformer. A 10kVA, 0.415 kV prototype distribution transformer has been acquired and connected to three residences for data acquisition. A data acquisition system has been developed to monitor and record the parameters of the prototype transformer for 14 days. The parameters, monitored in real-time include load current, phase voltage, transformer oil level, ambient temperature and oil temperature. The acquired real-time data of the transformer is validated with the standard measuring instrument. An algorithm was developed to transmit and log the data to ThinkSpeak cloud server via node MCU (ESP 8266). Results obtained in this study, which can be visualized via the graphical user interface of ThinkSpeak, indicate that the proposed scheme can acquire vital data from the distribution transformers and transmit the information to the monitoring centre.

    Sizing and Implementation of a Standalone Solar Photovoltaic System for a Three-Phase Submersible Pumping Machine
    (Faculty of Engineering, Ahmadu Bello University, Zaria, Nigeria, 2023-04) Abdullateef, Ayodele Isqeel; Issa, Abdulkabir Olatunji; Sulaiman, Abdullah; Issa, Abdulrasheed Yinka; Salami, Momoh Jimoh Eyiomika; Onasanya, Mobolaji Agbolade
    The solar photovoltaic system is an alternative power supply source that could aid the economic growth of a nation. However, improper sizing of the system leads to a high installation cost and a low level of penetration in the energy mix. This study focused on the appropriate sizing and implementation of a standalone solar system for a three-phase pump machine in a farm in Ilorin, Nigeria. The pump rating was determined manually as 20HP, with a flow rate of 180,000 L/h. Consequently, the daily load and solar global horizontal irradiance data were acquired and used for sizing the PV system using HOMER Pro software. Fifty-six solar panels with a total area of 120.4 m2 were proposed and installed to achieve a total power of 22.4 kW required for the machine's operation. The levelised cost of energy was 0.4007 $/kWh as against the cost of energy when the farm was running on generators with an energy cost of 4.170 $/kWh. The economic analysis of the system for the farm shows the Net present cost and cost of energy of the system configuration are $28,341.91 and 0.4007 $/kWh, respectively.
