Fault recordings analysis in web-browser
Cloud-based solutions can not only be used in one's everyday life. Now relay protection engineers can use them while on duty. PowerGrid App allows to perform fault recordings analysis using a web-browser.
First step to start off with the application is to upload fault recordings that you have: COMTRADE, CSV, SEL CSV formats are supported. Analog channels which you are interested in may be visualized in two areas; visualization of binary signals is performed in a designated area.
Service allows to synchronize recordings and to add calculated signals, based on measured ones. Vector diagram generation feature is also available.
Besides that Fast Fourier Transform (FFT) function is available which allows to perform harmonic analysis of the signal on the specific time interval.
