Practical example of an air gap measurement

Air gap measurement on hydropower generators

A manufacturer of hydropower plants wants to optimize the reliability and efficiency of its systems. A critical parameter during start-up and operation is the air gap between the rotor and stator. This gap directly influences the performance, efficiency and operational safety of the plant. The manufacturer integrates a Delphin hardware and software system into its systems, combined with capacitive sensors for precise air gap measurement and monitoring. This leads to greater operational reliability and system availability, thus reducing the risk of failure
