NRG Systems Expands into Condition-Monitoring for Turbines

Condition-monitoring systems use sensors to detect component faults, allowing maintenance professionals to avoid equipment failure

Hinesburg, VT (USA)—Building on three decades of expertise in sensor-based wind measurement, NRG Systems has expanded its offerings to the wind energy operations and maintenance segment. Its patented TurbinePhD™ system monitors the health of turbine components for more cost-effective operations and maintenance.


"Our system borrows technology from the aerospace industry to diagnose early-stage wear —months in advance of a fault—and then to accurately estimate the remaining useful life of each component," said Eric Bechhoefer, chief engineer at NRG Systems. "We also eliminate the need for a diagnostic engineer by integrating data into a single, readily understandable health indicator for each component. The data can be read and acted upon by anyone."

Condition-monitoring systems use sensors to detect component faults, allowing maintenance professionals to avoid equipment failure. TurbinePhD uses digital signal processing techniques to detect component wear before it escalates into a fault. Smart sensors with embedded processors use algorithms to diagnose problems and then transmit that data to a secure website, where the maintenance professional can see easily-understood turbine health indicators (THI™) for each component and drill down to view all of the supporting data.

NRG Systems is finalizing beta installation of the TurbinePhD system and expects to release the product this summer. The system is patented under U.S. patent number 8082115. For more information visit http://turbinephd.nrgsystems.com/.

GreenFasten™ solar panel roof mount hardware, watertight, USA made

GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
