Testing Techniques

Focusing on the application technique of the phase testing techniques in cell identification, the analysis to the morphological structures of the leucocytes is done, and the physical models with nucleus of white blood cells are built. Based on the VirtualLab and numerical simulation techniques to systematic study on the distribution of the phase of the the leucocytes, the inside and outside morphological structures of the leucocytes and the main characteristics of the models are found. Thus, the phase testing application has been expanded. The light phase distribution analysis of biological cell is expected to become a new tool to detect the biological cell.

Discharge Detection

A portable acoustic-electric detection system for GIS partial discharge is developed. This system integrates both high and low-speed data acquisition devices, and is capable of multichannel joint detection of ultra-high-frequency and high-frequency current as well as ultrasonic signal generated during the GIS partial discharge process. The software of this system is developed based on LabVIEW. It can successively capture, acquire and store the pulse waveform of partial discharge, calculate the phase of discharge pulse and realize time-frequency analysis and amplitude-phase distribution analysis of PD signals at the same time. By calculating the time difference of multi-channel ultra-high-frequency (UHF) signals and of PD ultrasonic signals or the time difference between the two, the system is able to locate the PD source. This system has been applied to on-site partial discharge detection of 220kV and 500kV GIS substations, and the test results have verified the performance of the system.
