Through the cooperation of the regional relativity and output volatility, we can know the relationship of the regional relativity and output...

With the Cross Linked Polyethylene (XLPE) power cables increasingly widely used in urban power transmission and distribution network, the reliable operation of XLPE insulated power cable line is becoming more and more important for economic and social development. [1] And there is a need to ensure the...

The RFID (Radio Frequency Identification) can be defined as Automatic identification technology which uses radio-frequency electromagnetic fields to identify objects carrying tags when they come close to a machine reader. In this paper authors designed the analog part using frequency 13.56 MHz in the...

This paper describes the 'buffering system in the RFID sensor tags'. Buffer circuit function is used in the data selection as a buffer. Two-sensor output which is an analog signal by a multiplexer owns a possibility of a very low value. The buffer circuit is required to maintain the signal in order to...

This paper introduces application of all-fiber optical current transformer to 10kV high voltage electric energy meter, proposes new application of 10kV current sampling by all-fiber optical current transformer, analyzes technical advantages of new 10kV high voltage electric energy meter and makes scheme...

Wavelet analysis and detection of modulus maximum are usually used to extract fault wave head. But for the actual transmission line, the existence of noise will affect the accurate extraction of wave head, leading to failure of location. To avoid the serious distortion caused by directly removing high...

China made a commitment in Sino-US Joint Statement on Climate Change that its carbon emissions will achieve the peak around 2030, and the percentage of non-fossil energy in primary energy consumption will reach 20% then. This paper aimed to analyze the how the targets could be achieved by the transition...
