Vibration Monitoring for Hydropower
Hydropower condition monitoring combines long-term machine trends with operating context. Turbine-generator trains and their auxiliary systems require different levels of monitoring and protection.

Rotating train
Suitable bearing and housing measurements can support condition trending.
Auxiliaries
Cooling, lubrication, pumps and fans are strong candidates for distributed monitoring.
Operating conditions
Load, hydraulic state, speed and transients need to be considered when interpreting vibration.
Practical measurement approach
Use VibSys where appropriate for condition monitoring and balance-of-plant assets. Main-unit machinery protection, overspeed and safety trips require the correct dedicated protection architecture.
Use VibSys with the IEPE sensor that fits the job
Istec VibSys is a four-channel platform for scalable vibration condition monitoring. Multiple units can be placed near selected machines as monitoring coverage expands.
Compatible standard 2-wire IEPE accelerometers can be used; VibSys is not locked to Istec sensors. This makes it possible to select sensors around measurement range, frequency response, temperature, environment and plant standards.
VibSys is intended for condition monitoring and diagnostics. Dedicated safety, trip and machinery-protection functions should remain on systems designed for those duties.
