Based on internationally accepted IEEE and CIGRE methods May be mounted directly on conductors (live or not) at suspension, spacer or damper clamps Ideal to use on lines fi tted with cushioned attachment devices Comes with a specifi c software for fast and easy confi guration and data retrieval Analyses collected vibration data in real time and provides built-in calculation of nominal conductor life expectancy High-resolution frequency and amplitude matrix (64 64) with user-programmable frequency and amplitude scales > Evaluates the in-situ vibration response of different line designs, tensions and hardware Estimates the nominal life expectancy of classical conductors subject to aeolian vibrations Rapidly identifi es sites with potential line vibration problems Supports the proper selection and positioning of anti-vibration devices such as Stockbridge dampers and spacers-dampers Helps in drawing up realistic maintenance and refurbishment programs >
