Conventional power stations remain the main source of energy production. To optimize safety, asset management and predictive monitoring, plant equipment is generally divide into two categories – Turbine generator sets and Auxilliary machines.

Modern measurement technology for machine maintenance
Important production line areas where PRÜFTECHNIK measurement technology is put to use include:

• Pumps
• Ventilators
• Turbines
• Generators

PRÜFTECHNIK condition monitoring expertise is employed in protecting the many auxilliary machines such as pumps and ventilators that are prevalent in power stations. Depending on the degree of requirement and importance, use is made of multi-channel online systems for safety monitoring and diagnosis functions (VIBROWEB, VIBROWEB XP) or offline systems (VIBSCANNER, VIBXPERT)  for portable data acquisition and analysis. As most power stations operate at different load ranges, the highly sensitive diagnostic monitoring with data acqusition based on order based plays a significant role. VIBROWEB series online systems are in a position to collect and consequently analyse measurement data in three different operating states. This helps detect machinery damage or peculiar operation at early stages.

The alignment of circular internal turbine elements during the overhaul or commissioning of turbines is carried out using high precision laser alignment systems. Using these systems reduces the time for the alignment of multi-stage turbine generator sets drastically. This reduces the machine downtime hence increasing machine availability. In addition to the alignment of turbines, PRÜFTECHNIK laser measurement systems are also used within the power industry for specialized applications that include:

• Determining levelness of foundations
• Alignment of rotating machinery
