متن کاملA Validation of the Spectral Power Clustering Technique (SPCT) by Using a Rogowski Coil in Partial Discharge Measurements
Both in industrial as in controlled environments, such as high-voltage laboratories, pulses from multiple sources, including partial discharges (PD) and electrical noise can be superimposed. These circumstances can modify and alter the results of PD measurements and, what is more, they can lead to misinterpretation. The spectral power clustering technique (SPCT) allows separating PD sources and...
متن کاملPCB Rogowski Coil for Electronic Current Transducer
The Electronic Current Transducer has been applied in power system for measurement and relay protection. To improve the stability of transducer and increase the coefficient of mutual induction of Rogowski coil, a novel Rogowski coil, namely PCB Rogowski coil was proposed. First, the relationship between conureuration parameters and electromagnetic parameters were analyzed, and simulated their r...
متن کاملLaboratory current transformer based on Rogowski coil
This paper cover the analysis and construction of current to voltage transducer based on Rogowski coil which satisfy the requirements of high-accuracy measurement of AC current (up to 20 A at power supply frequency, with the aiming uncertainty of 100 parts per million). Primary source of ac current uncertainty measured by this type of transducer is nonuniform density of turns which, in case of ...
متن کاملHigh Frequency Characteristic of Rogowski Coil
According to the transfer impedance getting from distributed parameter model,we analyse the influences of magnetic conductivity , the number of turns ,capacitance to the shield and interturn capacitance on the high frequency characteristic of Rogowski coil through theories and simulations. Simulation shows that there are a series of zeros in high frequency band, but on the whole, the high frequ...
