Abstract: A system and a process for detecting oil quality includes a light source configured to generate light within an oil container and a sensor configured to detect light from the light source after it has traversed through the oil in the oil container and generate an output signal. The system and process further includes a monitor configured to receive the output signal from the sensor and determine an oil quality of an oil in the oil container.

Abstract: An electrical arc detector for switchgear includes a fiber-optic cable configured to receive light emitted from switchgear at a first end and transport the light to a second end. The detector further includes a sensor arranged adjacent the second end of the fiber-optic cable configured to sense the light and generate an electrical signal, and analog-to-digital converter configured to convert the electrical signal to a digital signal, and a processor configured to monitor the digital signal and at least one of transmit information related to the digital signal, store information related to the digital signal, and take action based on the digital signal.

Abstract: To improve forming properties of laminated structures comprising two sheets of a non-ferrous metal alloy connected by an adhesive, which hardens at heating and between which an adhesive layer is bonded to the metal sheets, a new sequence of heat treatments is proposed. The alloy of the sheets is in soft condition before the sheets are bonded to each other. The bonding temperature and time are selected such that it remains substantially in soft condition and only after forming further heating is applied to obtain hardening of the alloy sheets.
