The TOR-8 natural ester-based insulating fluid residual gas content tester, manufactured by GlobeCore, is designed to measure the total gas content in insulating fluids used in power transformers and other oil-filled electrical equipment. Monitoring residual gas content is important for evaluating fluid quality, particularly after vacuum degassing and other treatment processes.
The TOR-8 uses a vacuum extraction method to release dissolved gases from an insulating fluid sample and determine their total volume. The measurement results help assess the effectiveness of degassing and determine whether the fluid meets the required gas content specifications.
Excessive dissolved gas content can adversely affect the dielectric properties of insulating fluids and may indicate the need for additional treatment. However, measuring total gas content alone does not identify individual gas components or determine the type of transformer defect. Such diagnostics require additional methods, including dissolved gas analysis.
The TOR-8 features a digital display and a straightforward control system that simplifies measurement procedures. Its compact design makes it suitable for use in electrical laboratories, substations, and transformer maintenance facilities. Components in contact with the tested fluid must be compatible with natural ester-based insulating liquids to ensure reliable operation.
Regular residual gas content testing with the TOR-8 helps verify insulating fluid treatment quality, support maintenance decisions, and maintain reliable transformer operation.
