investigation of gassing behavior, electric and dielectric properties of different insulating fluids.
ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...
15 صفحه اولSignificant effect of sorbed water on the electrical and dielectric behavior of graphite oxide
This paper reports the unexpectedly strong effect of 4 wt% additional sorbed water on the electrical and dielectric properties (50 Hze2 MHz) of graphite oxide (GO) containing 18 wt% sorbed water. Water contents of 18 and 22 wt% (designated GO18 and GO22, respectively) are compared, with the former obtained by heating at 60 C (3 h) immediately before testing. The additional water increases the c...
متن کاملDielectric properties of low-water-content tissues.
The dielectric properties of two low-water-content tissues, bone marrow and adipose tissue, were measured from 1 kHz to 1 GHz. From 1 kHz to 13 MHz, the measurements were performed using a parallel-plate capacitor method. From 10 MHz to 1 GHz, a reflection coefficient technique using an open-ended coaxial transmission line was employed. The tissue water contents ranged from 1 to almost 70% by w...
متن کاملEffect of salinity on the dielectric properties of water
The complex permittivity ∈=∈′− j∈′′ of distilled water and NaCl solutions of concentrations varying from 5000 to 35000 ppm have been measured in the frequency range from 200 MHz to 1.4 GHz using a Vector Network Analyzer (VNA). The complex permittivity of saline water collected from Kanyakumari sea bank has also been measured in this frequency range. It has been observed that the dielectric con...
متن کاملConductance of Water-sorbed Activated Carbon: Differentiation of Flow Direction
The conductance of a piece of activated carbon immersed in water has been measured at several different temperatures. The upward and downward flow Qf water as well as the flow in the horizontal direction in the same piece was made possible by using various arrangements of the apparatus. The rate of increase in the conductance has been interpreted as the rate offlow of water into the pores ofact...
