Recognition and Location of Power Transformer Turn to Turn Fault by Analysis of Winding Imposed Forces

Turn to turn fault is one of the major internal failures in the power transformers that if it is not quickly detected, can be extended and led to a complete transformer breakdown. So, the diagnosis and location of the turn to turn fault of the power transformer, as one of the most important equipment in the power system, is the main objective of this paper. For this purpose, a detailed model of...

Stator Turn-to-Turn Fault Detection of Induction Motor by Non-Invasive Method Using Generalized Regression Neural Network

Condition monitoring and protection methods based on the analysis of the machine's current are widely used according to non-invasive characteristics of current transformers. It should be noted that, these sensors are installed by default in the machine control center. On the other hand, condition monitoring based on mathematical methods has been proposed in literature. However, they are model b...

Turn, Turn, Turn: Predicting Turning Points in Economic Activity

strength and duration, that have, so far, characterized economic activity. January 31, 2001: Preliminary real GDP growth for the fourth quarter is barely above 1 percent, more than 4 percentage points below what is was only two quarters before and about 7 percentage points below its level in the third quarter of 1999. Much of the press, and some forecasters, predict that the first quarter of 20...

A Turn-by-turn Vertical Profile Monitor

A turn-by-turn vertical beam profile monitor has been developed at the Cornell Electron Storage Ring (CESR). The instrument optically images the vertical beam distribution with an array of optical fibers that transport visible synchrotron radiation to an array of photo-multiplier tubes. Each PMT signal is recorded by a turn-by-turn data acquisition system. With this instrument, we compare profi...
