Almost all GPS signal clocks show a periodic fluctuation. Harmonics in GPS satellites are a well-known feature, such as 3-, 4-, 6- and 12-h terms, accurate extraction of these harmonics are helpful to improve the clock modeling. The inaction method (IM) originating from the concept of normal time–frequency transform (NTFT) can precisely extract the periodic signals which significantly present the...
A new current decomposition method based on multiple linear regression is presented. The time-domain equations of every current component on the applied voltage are deduced based on an improved equivalent model of the metal–oxide surge arrester (MOA). The capacitive current compensation method and the proposed method are used to decompose the total leakage current and to study the influence of the...
The prominent feature of the degradation of metal oxide surge arrester is an obvious increase of the resistive current, especially its fundamental and third harmonic, so it is very important to measure the resistive current. In this paper, a new method for the measurement of the resistive current is presented. At first, the time-domain equations of the resistive current, the capacitive current and...
