Abstract
The failure of mineral oil‐filled transformers has been involved in numerous fire and explosion incidents during operations. The power industry has developed online dissolved gas analysis (DGA) monitoring systems capable of diagnosing transformer faults continuously. This study has established new test procedures and pass/fail criteria to evaluate the accuracy of online H2 monitors, resulting in the creation of a new approval standard.
期刊介绍：
Process Safety Progress covers process safety for engineering professionals. It addresses such topics as incident investigations/case histories, hazardous chemicals management, hazardous leaks prevention, risk assessment, process hazards evaluation, industrial hygiene, fire and explosion analysis, preventive maintenance, vapor cloud dispersion, and regulatory compliance, training, education, and other areas in process safety and loss prevention, including emerging concerns like plant and/or process security. Papers from the annual Loss Prevention Symposium and other AIChE safety conferences are automatically considered for publication, but unsolicited papers, particularly those addressing process safety issues in emerging technologies and industries are encouraged and evaluated equally.
