What is BS EN ISO 10704:2015?

In the world of technical standards, BS EN ISO 10704:2015 holds a significant position. This international standard provides guidelines and recommendations for the analysis of gases dissolved in insulating oils. It offers a systematic approach to determine the concentration of various gases, helping engineers and technicians assess the condition of high-voltage electrical equipment.

Key Objectives and Scope

The primary objective of BS EN ISO 10704:2015 is to enable accurate diagnosis and monitoring of electrical equipment by analyzing the gas content in insulating oils. The standard covers a wide range of gases, including hydrogen, methane, ethane, ethylene, acetylene, carbon monoxide, carbon dioxide, nitrogen, and oxygen. By measuring the concentration levels of these gases, potential faults or abnormal operating conditions can be identified and appropriate actions can be taken timely.

Methodology and Testing Procedures

This standard outlines precise methodologies for gas detection and measurement from oil samples, providing detailed instructions to ensure reliable and consistent results. The document emphasizes the importance of proper sampling techniques, handling, and preparation of oil samples before analysis. Additionally, it defines gas chromatographic techniques, calibration procedures, and statistical methods used to interpret test results.

BS EN ISO 10704:2015 also addresses safety precautions and quality control measures necessary for accurate and valid testing. The standard advises on instrument calibration, reference standards, and proficiency assessment to enhance the reliability and reproducibility of the analytical results.

Benefits and Applications

Adherence to BS EN ISO 10704:2015 offers several benefits, including increased equipment reliability, optimized maintenance scheduling, and reduction in electrical failures. Regular monitoring of gas content allows for early detection of potential faults, preventing unplanned downtime and costly repairs. The standard finds applications in a variety of industries with high-voltage electrical equipment, such as power generation, transmission, and distribution sectors.

Furthermore, compliance with this standard ensures uniformity and consistency in gas analysis practices worldwide, facilitating effective communication and comparison of results among different laboratories and organizations.
