2025-03-25T17:43:52+07:00

Non-standard electrical installations often cause fires due to short circuits. RCBO (Residual Current Circuit Breaker with Overcurrent Protection) is known to enhance electrical installation protection. People often neglect the dangers of non-standard electrical installations. This study designs a demonstration tool for an electrical protection system. The demonstration tool is intended to show that using non-standard electrical devices is hazardous. It effectively demonstrates the effectiveness of RCBO in protecting against abnormal conditions. The design includes testing MCB (Miniature Circuit Breaker) and RCBO as circuit breakers. The results show that RCBO is effective in minimizing electrical risks and plays a crucial role in protecting electrical equipment. In the short-circuit test, the RCBO tripped in 1.33 seconds, while the MCB tripped in 5.19 seconds. In the leakage current test, the RCBO was able to detect a leakage of 30 mA. Additionally, in the overload test at 1.8In, the RCBO tripped in 9.4 seconds, whereas the MCB tripped in 33.2 seconds. Thus, the RCBO demonstration tool created can visualize electrical hazard factors such as short circuits, leakage currents, and overloads. Moreover, the combination of RCBO and MCB is more effective as protection.

ADDITION OF FLOW TRANSMITTER AS A CONTROL TO ENHANCE THE ACCURACY OF OIL PRODUCTION READINGS

2025-03-25T19:33:28+07:00

This research aims to evaluate the effectiveness of adding a flow transmitter as a control in improving the accuracy of readings of petroleum production results, which previously used transmitter levels as a control. The use of transmitter levels as a control has been shown to affect watercut analyzer readings, resulting in lower and less accurate flow counts. In this research, a comparative analysis was carried out between the control system that uses a level transmitter and the control system that uses a flow transmitter. The methods used include field data collection, statistical analysis, and performance evaluation of the two systems. The results showed that the use of a flow transmitter as a control could increase the accuracy of flow readings by about 13.2% compared to the previous control. This improvement not only improves the accuracy of flow measurements, but also has a positive impact on operational efficiency and management of petroleum resources. This research is expected to contribute to the petroleum industry in an effort to improve a more effective and efficient production measurement and control system.
