Two general loss formulations have been proposed in this paper for total system real power loss and series reactive power loss and series reactive power loss. These are expressed as quadratic functions of both real power and pv-bus voltages. Quadratic expression for series reactive power loss has...
According to Joule’s heating formula, the heat energy generated is proportional to the time when the electric current and electrical resistance are constant. Power loss due to heating is the main drawback preventing the use of incandescent lamps We are in the process of transitioning into more ...
Now we can calculate the reactive power Q = VIsinφ VAR This reactive power can now be supplied from the capacitor installed in parallel with the load in local. The reactive power of acapacitorcan be calculated using the following formula: IMPORTANT: Inpower factor improvement, the reactive pow...

4: path loss and signal attenuation caused by obstacles, that is, signal energy loss between the transmit antenna and receive antenna, in dB Radio transmit power: includes radio transmit power of the AP (1) and that of the STA (7). During WLAN planning, ensure that the sum of the trans...
The impact of HRES integration into the distribution system is to minimize the real power loss, and the voltage deviation is subjected to satisfy all of the operational constraints, such as limits of node voltages (\({V}_{i}^{min}\le {V}_{i}\le {V}_{i}^{{\text{max}}}\)), li...
Expressions are provided which describe the frequency dependence of the power loss. The influence of the permeability and the physical dimensions is considered. Formulae are given for the impedance of the cylinder in different frequency regions. Numerical results are presented to show the behavior...

The rated output current IN must be reduced to ensure that the maximum heat loss or heat sink temperature for higher pulse frequencies is not exceeded. When the correction factor kf for the pulse frequency is applied, the rated output current IN that is valid for the selected pulse frequency ...
The formula for BEP is earnings before interest and taxes divided by total assets. BEP is similar to the return on assets (ROA) metric. Understanding Earning Power Earning power takes into account several elements, including a company’s total assets, plus recent growth or loss trends. ...
