The concept of Dynamic P-F Curve is introduced to represent Equipment Degradation with varying operating conditions. The conventional P-F Curve is static, difficult to use for maintenance planning, and needs to be re-analyzed with new readings.
Dynamic P-F Curve connects with the streaming sensor data & uses algorithms to plot automatically. It gives the following advantages:
- Changes with varying stress & environmental conditions
- Maintenance plans can be tailored in real-time
- Systems with complex sub-assemblies can be represented in a single plot*
- Alarm points can be moved to accommodate Repair time
