“…In this research, a test was conducted to examine the relationship between the number of operating frequencies and the age of the oil with Oil Dielectric Strength (ODS) kV using the ASTM D1816 standard [19]- [21]. The case study was held at the Power Generation and Transmission (PGT) electrical substation of PT.…”

The electricity distribution breakdown can be caused the service life and operating frequency of Oil Dielectric Strength (ODS). Hence, it requires a study due to the spare part is difficult to find. This paper aims to test the ODS on Oil Circuit Breaker (OCB) of 13.8 kV aged between 29 to 43 years. The test used the ASTM D1816 standard to analyze the effect of oil life and circuit breaker operating frequency on the physical, color and strength of ODS. For the visual test used the ASTM D1524 standard. The color test based on the ASTM D1500 standard. From the test results, it can be seen that 6DN F1 was yellow-black in colors. The color level was from 0.5 to 6, which was a striking color difference. This happens because it had been operating for 3 years with a frequency of 2 manual open times and 11 trips with a large normal load of 206A. In the 8D F7 feeder, there was also a decrease in breakdown voltage, which was far from 45.6 kV to 9.7 kV. Therefore, the oil was declared failed due to below the minimum standard of 27 kV. Based the validity test, the six samples were still within the allowable limits based on ASTM D1816 with the range value being below 92%. This means that the six samples were valid.

“…Then, the sensor position was used as a reference point of measurement. The water surface distance data from the sensor was sent to the controller (Arduino UNO ATMEGA328) [40]. The formulation and calculation based on the rectangular weir box design dimensions, the parameters needed for measuring water discharge based on ASTM standards can be calculated [41]- [45].…”

“…The computer was used for monitoring data acquisition on the water flow measurement system that was connected to the Arduino UNO ATMEGA328 microcontroller. This system used an ultrasonic-based distance sensor or the ultrasonic range meter HC-SR04 with the ability to accurately measure 2 cm to 400 cm [40]. The duration of the ultrasonic signal travel time was sent until it was received back.…”

“…Based on the ease of using PLX-DAQ Excel data acquisition [27], which was connected to the ATMega 328 Microcontroller, which has a RISC (Reduced Instruction Set Computer) architecture that has a faster data execution process than a microcontroller with a CISC (Completed Instruction Set Computer) architecture. Other features possessed by ATMEGA 328 were having an EEPROM (Electrically Erasable Programmable Read-Only Memory) with a capacity of 1KB as a place for semi-permanent data storage [39] [40]. The EEPROM can still store data even though the power supply is off.…”

The data acquisition for monitoring the water flows in real-time, which is available at any time, is needed for water management purposes. This paper aims to build a prototype of a water flow measurement system in an open channel of a rectangular weir box design using the American Standard Testing and Material (ASTM). This research contribution is a development of a water flow measurement, which can be used as a simulator for studies on measuring water discharge in real cases in the field. More, this instrument is based on the data logger using Arduino, which is designed at a low cost and is easy to use. This water flow equipment can be measured in real-time, so that data information can be directly obtained for analysis. The design of a data acquisition system can display water discharge data in real-time from time to time and allows data storage (data logger) as historical data that can be displayed whenever needed. The Arduino UNO ATMEGA 328 microcontroller was programmed to read the HC-SR04 water level sensor on a distance-based weir box displayed on the LCD. Monitoring and recording of data were displayed on the Parallax Data Acquisition tool (PLX-DAQ) software add-on for Microsoft Excel in real-time. The prototype was able to provide a real simulation of the water flow calculation process until the maximum design capacity of 784,384.87 liters per day. Tests on the overall performance of the water flow measurement system were carried out using flowing water media at 3 different flow conditions based on time. From the average log data of the tests carried out, the deviation of the measurement data against the ASTM calculation theory on average of 0.8 liters/minute. These results were quite good because of the 16,502 liters of water measured. The difference in the calculation results was only 1.003 liters.
