This article presents an online monitoring system for power\ntransformers developed and evaluated on several transformers at EDF. It\ncombines acoustic, electrical and chemical measurements of partial\ndischarges to establish a diagnostic of the transformers and generate an\nalarm if admitted thresholds ...
An on-line monitoring system of the current in the grounding loop of the transformer's core is introduced.This system can real-time monitor the grounding current of the transformer's core and store the historical data.When the grounding current exceeds the national standard,the system will genera...
The utility model discloses an outgoing-line rising base on a middle part of a transformer, which comprises a first barrel body which is arranged horizontally and a second barrel body which is vertically connected with the first barrel body; the first barrel body is connected with the second ...
Please Use Browser Search Tool On Listings Power Transformers are used in transforming the voltages from one level to the next. Power Transformer can be divided into 3 basic categories as listed below. The basic difference between these are the frequency of the electrical signal and the size. Th...
2 use a color-line prior to removing haze. Berman et al. find a haze-line prior4 based on the observation that one haze-free image can be presented by a small number of color clusters. However, all these priors are simple, and cannot be held in real word complex scenes. Transformer ...
If necessary, clear the temperature control signal during the no-load switch-on period. The insulation between the line or transformer and the ground is faulty. Power off the system. Check whether the line is damaged, aged, flawed, or damped, and whether there are foreign objects (especially...
Development of Intelligent On-line Monitoring Instrument for Power Transformer Considering such operation characteristic of power transform as wide distribution, unattended operation, it is very urgent to realize the on-line state monitoring and fault diagnosis for transformer during its running through netw...
Off-line- and on-line-monitoring of power transformers using the transfer function method The transfer function concept is well known as an additional method to evaluate the impulse test of power transformers in the test laboratory. Another appl... T Leibfried,K Feser - Conference Record of the...
