This article is devoted to the substantiation of the possibility of electrical capacitance measurement utilizing equations that are based on the approximation of scattering ellipse, formed by signals proportional to the current flowing through the capacitive tested object and voltage drop on the tested object.
Broadband transfer power wattmeter with the correction of the own consumption error for measuring the active power against the background of large reactive components in the radio frequency range is considered in article. Objects of research are electromagnetic elements (chokes / transformers), operating at high frequencies till units of megahertz and are inherent in the strongly distorted forms of signals. Features of the construction of the input link of the wattmeter of transfer power with the middle point of the shunt are described.
