Leine Linde Systems GmbH has announced its new ADSR product, a slip ring for wind turbines that has an integrated diagnostic system for analyzing condition and predicting remaining service life.
Pitch slip rings, which supply the rotor hub with voltage, signals and data, are subject to wear, and Leine Linde says the ADSR's diagnostic system continuously monitors the contact systems and other key functions of the slip ring, enabling condition-based maintenance.
The ADSR's integrated sensors measure vibrations, the level of voltage and current, revolutions, internal and external humidity, and temperature. The company says the information and warning messages sent via the diagnostic system are displayed by an LED on the slip ring and made available using network interfaces. Maintenance personnel can use a browser-based Web monitor to view the current status, as well as reports and analyses.
