This paper describes a new digital wireless data acquisition system that can be used to measure electro-magnetic interference (EMI) in power stations or other similar harsh environments. It comprises of a Remote Acquisition Unit (RAU), a Wireless Data Communication Network (WDCN) and a PCbased Control Platform As a front end of the field-distributeddata-acquisition system, RAU captures, digitizes and stores the EMI signals in its memory and sends the information to the PC using the Wireless Data Communication Network. The WDCN acts as a bi-directional data communication link between the RAU & the Control platform. It is based on Bluetooth technology and has a point-to-multipoint topology. The RAU serves as the acquisition function of a Digital Storage Oscilloscope (DSO) while the Control Platform carries out the display & control function of a DSO. The whole system, as such, may be regarded as a 'Computerised Wireless Oscilloscope'. The system offers an innovative way for implementing monitoring, protection and testinG systems based on wireless sensor networks

“…However, as an emerging technology, the industrial applications of RCTs have encountered some problems . In particular, during the operation of the disconnecting switch (DS) , the output of RCTs will be distorted since the coil and the electronic components of sampling unit are vulnerable to the very fast electromagnetic disturbances . From a theoretical point of view, an RCT is ordinarily composed of a Rogowski coil (RC), a sampling unit, and a merging unit .…”

Switching operations of the disconnecting switch (DS) within high‐voltage gas‐insulated substations generate very fast transient electromagnetic interferences. Fast front pulses induced by these interferences produce high‐level transient currents that can lead to disturbed voltage output of Rogowski coil current transformers (RCTs). Predicting the transient characteristics of RCTs requires the implementation of accurate simulation models of the Rogowski coil. Concentrating on the DS operation process, this paper analyzes the performance of the lumped parameter model (LPM) and the distributed parameter model (DPM) available in the literature by means of comparisons in the time domain and frequency domain between two models, as well as comparisons between simulation results and measurement results in terms of the waveform properties and the distribution of amplitude. It is confirmed that the simulation results based on the DPM show better agreement with the measurements than those based on the LPM. It is also indicated that the maximum amplitude of the RCT output is approximately 580 mV with the dominant frequency of 2 MHz during the fast transient. © 2018 Institute of Electrical Engineers of Japan.
