摘要： Provided are an oil condition determination system and an oil condition determination method that are capable of continuously determining the oil condition when oil is partially replaced or oil is added. An oil condition determination system includes a measurement unit and a determination unit. The measurement unit periodically measures a resistance value of oil. The determination unit periodically determines a condition of the oil based on the resistance value, stores a local maximum value of the resistance value, determines that the condition of the oil has changed when a difference between the local maximum value and the resistance value becomes greater than or equal to a first threshold value, and initializes the local maximum value and updates the first threshold value when the amount of change in the resistance value per unit time becomes greater than or equal to a second threshold value.

摘要： A chip detection system for an engine fluid system includes an emitter located in a first position proximate to a fluid passage of the engine fluid system, the emitter including a radioactive source that generates ionizing radiation particles and transmits the ionizing radiation particles through a liquid within the fluid passage. A detector includes a detecting element located in a second position relative to the fluid passage with the liquid disposed between the emitter and the detector. The detecting element generates an electric current in response to the ionizing radiation particles contacting the detector. A controller is in communication with the detector to receive the electric current generated by the detecting element. The controller is operable to detect chips in the liquid when the electric current generated by the detecting element is greater than a threshold value of the electric current.

摘要： A lost circulation material is placed in a cavity. The cavity is defined by an inner bore of a cylindrical wall, intermediate of a piston and a screen. A distance between the piston and the screen is defined as the height of the cavity, which is adjustable. The piston is slid longitudinally, such that the piston comes in contact with the lost circulation material. The lost circulation material is heated to a specified test temperature mimicking a downhole temperature. A compression test is performed on the lost circulation material. The compression test includes flowing a test fluid into the cavity and applying force on the piston to pressurize the test fluid to a specified test pressure mimicking a downhole pressure. The force on the piston is released. The pressure of the test fluid and the height of the cavity are measured throughout the compression test.

摘要： The present disclosure relates to a simultaneous detection method and system for dissolved gas and partial discharge in insulating oil, and belongs to the field of electrical devices. The method includes the steps: freely diffusing the dissolved gas in the insulating oil to an F-P optical fiber interference cavity through an oil-gas separation membrane; coupling pump light and probe light into the F-P optical fiber interference cavity through a frequency division multiplexer; making, by an optoacoustic effect of the dissolved gas stimulated by the pump light and an ultrasonic wave generated by the partial discharge, the oil-gas separation membrane vibrate; detecting, by the probe light, vibration of the oil-gas separation membrane, which changes a cavity length, wherein when the probe light is reflected by the oil-gas separation membrane, an interference signal is generated due to the change of the cavity length.
