Abstract
Hydrogen can be released during the thermal decomposition of organic materials, therefore, monitoring its level in the working industrial high-voltage transformer oil allows you to identify the development of degenerative processes in advance, because these processes can lead to an accident in the future. In experiments has shown that highly sensitive and small-sized field effect gas sensor based on the metal-insulator-semiconductor structure can be used for measuring of Hydrogen in oil with direct contact of its structure with transformer oil. Given the harsh environmental conditions of hydrogen measurement the field effect capacity type gas sensor were fabricated by using laser micromilling technique for fabrication compact ceramic surface mounting device package and microheater for sustentation working temperature of metal-insulator-semiconductor structure.
Highlights
Transformers are one of the main components of the complex equipment of many energy or industrial enterprises
The main characteristics of transformer oil, its purity and useful properties determine the performance of transformers
The ability of the oil to maintain its original properties in operating equipment during operation is called the stability of transformer oil
Summary
Transformers are one of the main components of the complex equipment of many energy (power plants, substations, converting devices) or industrial enterprises. In experiments has shown that highly sensitive and small-sized field effect gas sensor based on the metal-insulator-semiconductor (MIS) structure can be used for measuring of H2 in oil with direct contact of its structure with transformer oil. A schematic representation of the field-effect gas sensor is shown on Figure 1 and described in work [7].
