The CBV-8 uses a new method of vibration analysis developed by Hydro-Québec and commercialized under license by Zensol.
This new instrument will allow the maintenance crew to detect mechanical anomalies in the circuit-breaker drive mechanisms and other moving parts in the interrupting chamber that should be inspected and overhauled.
The CBV-8 is used in conjunction with accelerometers. Its high sampling frequency of at least 150 kHz allows to catch a large variety of mechanical anomalies.
The CBV-8 comes with powerful and user-friendly software : CBV WIN used for recording the test sequence and DVA for analyzing the defect severity and plan further maintenance actions. It integrates many calculation functions including: noise suppression, amplitude and time deviations between measured and reference signals, frequency spectrogram depicting relevant frequencies.
