This document contains an electrical engineering table designed by Fredrick Kendrick to calculate values for parallel or series circuits. The table includes voltage, impedance, resistance, power, and conductance values for 5 resistors labeled R1 through R5, as well as total values. Formulas are also provided to calculate resistance, power, current, and voltage values for the circuits.
Many challenges exist with turbine blade inspections -- Cracks and crack initiation in the blade attachment serrations need to be reliably detected. Complex geometry of the component is a very challenging factor for inspection design. In-situ inspection without blade removal is required, thus limiting blade access. This application presentation highlights a recommended solution with techniques to overcome the challenges.

The increasing needs in term of energy production lead to new rotor shafts designs with larger dimensions. A new generation of nuclear power plants is already being deployed worldwide with such heavy components. Their implementation requires new inspection tools in order to guarantee the public safety and to ensure the quality of these critical parts.
This presentation addresses the implementation and validation of new solutions for large mono-block rotor shaft forgings.
A basic understanding of Vibration analysis of machinery and structures. I prepared this slides for one of my training for clients in the military many years back. Its not updated yet, but gives readers idea of the practical fundamentals of vibration analysis.
Case Study - VTK Fan/Blower Vibration Analysis & Rotor Balancing w/ Motionics...Motionics, LLC
VTK is a fan and blower manufacturing and maintenance company in the Netherlands. Operators at VTK frequently check fan and blower vibration conditions and perform balancing work if an imbalance is detected. Motionics wired 2CH vibration analysis and rotor balancing kit integrates a DAQ system on an iPad case and allows operators to complete vibration checks and rotor balancing easily on an iPad.

Risers are critical components in the upstream segment of the oil & gas industry. Riser bolts require regular inspections for crack detection. Removing bolts is time consuming and many manual inspection techniques are ineffective.
This presentation provides a recommended solution that can improve the efficiency and reliability of the inspection with an increased detection capability, permanent records and more.
The critical equipment used in deepwater drilling operations is subjected to harsh environmental factors such as loop currents, extreme weather, and high seastates. It is important to understand the effects these environmental variables have on subsea wellhead and conductor integrity.
Through the use of drilling riser monitoring systems (DRMS) operational insight into the real-time status of critical equipment such as the Wellhead, Conductor, BOP, and Riser can be instantly evaluated allowing for safe and efficient decision making.
A business case and ROI justification is presented in order to show that a DRMS can reduce Non-Profitable Time (NPT) and Invisible Lost Time (ILT) and is financially justified by saving as few as 1 day of rig time.

Power Performance Optimization using LiDAR technology : India Pilot Project R...Karim Fahssis 卡卡
Presentation given by MeteoPole's CEO Mr. Karim Fahssis at the IPP summit in November 2014 Delhi showing the results of the India Power Performance Optimization Pilot Project with Continuum Wind Energy on Surajbari wind farm project in Gujarat (Vestas turbines) with a proven +2.4% AEP increase after yaw error correction.
Development of a low cost test rig for standalone wecs subject to electrical ...ISA Interchange
In this paper, a contribution to the development of low-cost wind turbine (WT) test rig for stator fault diagnosis of wind turbine generator is proposed. The test rig is developed using a 2.5 kW, 1750 RPM DC motor coupled to a 1.5 kW, 1500 RPM self-excited induction generator interfaced with a WT mathematical model in LabVIEW. The performance of the test rig is benchmarked with already proven wind turbine test rigs. In order to detect the stator faults using non-stationary signals in self-excited induction generator, an online fault diagnostic technique of DWT-based multi-resolution analysis is proposed. It has been experimentally proven that for varying wind conditions wavelet decomposition allows good differentiation between faulty and healthy conditions leading to an effective diagnostic procedure for wind turbine condition monitoring.
