The data logger system plays an important role in research and development. In order to obtain valid data, the data logger must be reliable and effective. High investment costs are involved in acquiring a data logger, and choosing a suitable data logger is difficult. In this paper, a mobile data logger is developed by using Arduino-Uno. This mobile data logger is equipped with a GPS module, which provides accurate positioning in the collection of data. Laboratory and field tests were carried out to observe the performance of the mobile data logger system. The results showed that the performance of this system was acceptable.

Partial discharge (PD) monitoring system is considered as one of the most promising solutions for monitoring and detecting possible faults. PD is able to diagnose faults within the system in the most fundamental and simplest way. PD monitoring and measurement of high voltage equipment substations panel and power transformers have not gained the same attention in the electrical community as compared to those of rotating machines. PD tests are conducted on-site to verify the insulation of bushings, termination box and windings. The cost of an unexpected outage may be considerably more significant for a high voltage substation panel and power transformers system than just for a single motor failure. In this research, the electroacoustic PD monitoring technique is used, which is a combination of internal PD detection and ultrasound or surface PD detection was used. The testing equipment which will be used in this research is UltraTEV Plus+ equipment from EA Technology. Result shows the transient earth voltage (TEV) PD magnitude fluctuates with time. Significant high value of PD magnitude (> 19 dB) was detected and recorded at several switchgear panel and transformer. However, for the ultrasound or surface PD, from the monitoring and measurement record, no detection of PD signal was recorded at the UltraTEV Plus+ testing equipment

Wireless Online Atmospheric Electric Field Measurement System Based on Rotating-vane Electric Field Mill Muhammad Abu Bakar Sidik; Hamizah Shahroom; Zolkafle Buntat; Yanuar Zulardiansyah Arief; Zainuddin Nawawi; Muhammad ‘Irfan Jambak

One of the popular methods to measure atmospheric quasi-static electric field is by using rotating-vane electric field mill (REFM) sensor. By observing electric fields strength in atmosphere, occasion of lightning incident can be forecasted. This paper proposes an integration of REFM with an online wireless data monitoring system for long distance observation and data collection. This method reduces system costs by removing the computer and data logger on-site. Furthermore, it reduces the required man-hour to gather data from the REFM. The development includes hardware and software design in order to improve efficiency the atmospheric electric field measurement system. The contribution of this paper is the design of the electronic circuit which converts the ac signal from the REFM sensor to dc signal and then correlates the signal to the electric field strength in the vicinity. Subsequently the information is transmitted via a wireless data transmission system, using the Global System Mobile Communication (GSM) network. Using the proposed method, all the data from sensors can be observed and analyse immediately from any location.

Lightning air terminals are a very significant part of lightning protection system (LPS) for buildings, structures and facilities. With reference to the facilities requiring lightning protection the position, the apparent height, and the angle of protection of lightning air terminals determines the collection volume (CV) of the protected area. The CV of direct strike lightning air terminals can change due to facilities which are affected by natural disasters such as seismic tremor and flood. If such natural disasters do happen, there are possibilities that the facilities will not be fully protected from direct lightning strikes due to building and structure misalignment the aftermath of seismic tremor and flood related earth movement. So for the safety of equipment and personnel, lightning protection system efficacy assurance is necessary. Therefore, there should be a technique and device to monitor the variation of collection volume afforded by every lightning air terminal on buildings and structures after the occurrence of a natural disaster. This paper presents a new technique as well as a new device to monitor the collection volume variation. A part of the device was obtained from a recycled moveable television antenna. This approach is not only practical, portable and cost effective but also incorporating the idea of environmental protection and recycling of used plastic materials.

Development of Compact On-Line Partial Discharge Analyzer Assessing Nanocomposite Insulation Performance for Research Purpose Aulia .; Yanuar Z. Arief; Zulkurnain Abduk-Malek; Zuraimy Adzis; Nor Asiah Muhamad; Muhammad Abu Bakar Sidik; Zainuddin Nawawi

Analyzing on-line partial discharge (PD) data using commercially available spreadsheet application software like Microsoft Excel is possible but very difficult to do. The problem is because the PD data are quite long and depend on the sampling rate used during testing. Increasing the sampling rate will increase data samples in one cycle of 50 Hz waveform, and longer time is needed to analyze the data. A further problem is associated with compiling the PD data; Excel uses a large memory to run, plot and calculate the PD data for analysis purpose, and sometimes this leads to computer memory crash. Due to this problem, an alternative on-line PD analyzer (on-LPDA) needs to be developed. This paper reports on the performance of the software that was developed using LabViewTM 8.5. The result shows that the software can extract PD parameters like PD numbers, PD magnitude, and plotting PD pattern without large time and memory consumption, compared with Excel, and experiences no memory crash up to 125 mega sampling (MS) rate.
