Application Summary AI generated
This standard specifies procedures for measuring and evaluating radial shaft vibration on large land-based steam turbines and generators exceeding 50MW, specifically for units operating at 1500, 1800, 3000, or 3600 r/min. It is applied in power generation plants for commissioning, operational monitoring, and maintenance diagnostics to ensure machinery reliability and prevent excessive vibration that could lead to damage or unplanned outages. The standard provides vibration severity criteria and measurement methods tailored to these high-power rotating machines.
