چکیده
Abstract Capacitive Voltage Transformer (CVT) is an important measurement and protection equipment in power system, which has the characteristics of high electrical strength, large insulation margin reliable operation. During operation CVT, its upper lower capacitors, compensation reactors, lightning rods other components often have faults. The faults CVT can be found time by judging secondary voltage value. In this paper, abnormal fault introduced. Combined with test disassembly analysis, it determined that caused breakdown capacitor unit. Through simulation, paper studies typical change law voltage, puts forward threshold alarm providing reference for online monitoring.

Measurement Error Estimation for Capacitive Voltage Transformer by Insulation Parameters
Measurement errors of a capacitive voltage transformer (CVT) are relevant to its equivalent parameters for which its capacitive divider contributes the most. In daily operation, dielectric aging, moisture, dielectric breakdown, etc., it will exert mixing effects on a capacitive divider’s insulation characteristics, leading to fluctuation in equivalent parameters which result in the measurement ...

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
15 صفحه اولTransformer voltage control and Tap changing
The voltage control is performed by changing the turns ratio. This is done by provision of taps in the winding. The volts per turn available in large transformers is quite high and hence a change of even one turn on the LV side represents a large percentage change in the voltage. Also the LV currents are normally too large to take out the tapping from the windings. LV winding being the inner wi...
متن کاملConcept of Quasi-Capacitive Tapping of Bipolar Voltage-Controlled Oscillators
Generally, bipolar transistors have better performance than MOS transistors if higher transconductances for the same operating point or higher transition frequencies are required. On the other hand, compared to MOS transistors, bipolar transistors often have limited use in the design of VCO’s, due to a limited voltage swing across the resonator and therefore limited phase-noise performance. How...
