Magnetic Data Acquisition System (MAGDAS) is a system of a real-time magnetometer data logger deployed by Kyushu Sangyo University of Fukuoka, Japan as part of Japan’s leading contribution to International Heliophysical year of the United Nations. This paper proposed a cloud-based MAGDAS for the YU-8T magnetometer. MAGDAS is the system that measures and monitors the earth’s magnetic field or geomagnetic field. Converting the old system to the new system will provide the capability to monitor the magnetic field changes continuously due to the solar activities which are harmful to the electrical appliances. To verify the workability of the system, the data from the MAGDAS Langkawi and solar event was gathered to be compared with the developed system. The location where the measurement takes place is at Pusat Sukan UiTM Shah Alam, Selangor, Malaysia (geographic latitude and longitude: 3.00N, 101.00E, and geomagnetic latitude and longitude: 6.37S, 173.65E. This project consists of the YU-8T magnetometer system, hardware, software, and cloud-based web-server. YU-8T magnetometer measures the voltage of Earth’s magnetic field in the form of H, D and Z parameters to be stored in the data logger. The stored data was transferred to the cloud-based web-server through the Internet of Thing (IoT) for real-time monitoring.

This paper study the existent of geomagnetic induced current (GIC) in Malaysia. The location for GIC measurement is conducted at Tenaga Nasional Berhad (TNB) substation 33KV transformer in Malaysia. The measurement is taken at the neutral cable of the 33KV transformer which is grounded to the earth. In order to verify the result of the GIC existence, the data from GIC measurement is observed with the data from the Solar Wind and Magnetic field of the earth. The measurement is taken using the HIOKI MR 8870-20 memory recorder, CT6846-05 current clamper, and CT9555 sensor unit. The study is conducted to identify the existence of the GIC in Malaysian Power Network transformer before conducting a further study on the harmful effect of the GIC level in Malaysia on the transformer performance. The data collected from the study to analyze and plotted using MATLAB software for further observation on the GIC level.
