Formula for Voltage Regulation of Alternator. Voltage Regulation is usually expressed as a fraction or percentage of the terminal voltage on load. Hence in general, if V is the terminal voltage per phase for a given load and E o is the open-circuit voltage (i.e. no-load terminal voltage) per phase, then. Voltage Regulation = Eo-V V per unit.There are several ways to measure the load regulation of a DC power supply. Perhaps the simplest way is to select load resistors that will present the minimum load, the maximum current, and nominal load (half the maximum current) to the power supply. Connect them one at a time to the output terminals of the supply and measure the output voltage.A transformer could be tested under no-load and full-load conditions to determine its turns ratio, regulation, and efficiency. However, without fully loading the transformer, it is possible to perform two tests (open-circuit and short-circuit) from which all the important data can be derived. In this article, learn how to analyze the results of open-circuit and short-circuit …Percentage of line regulation can be calculated by = where V 0 is the output voltage and V IN is the input voltage and ΔV 0 is the change in output voltage for a particular change in input voltage ΔV IN. b) Load Regulation . In this type of regulation, input voltage is fixed and the load resistance is varying. Load regulation of the output voltage, V, is defined as: V/ V FULL LOAD X 100% Where ... This is the V in our equation. Parameter math in P5 and P6 is used to calculate load regulation. P5 takes the ratio of the amplitude (P4) to the loaded output voltage (P3). The ratio in P4 is multiplied by 100% using the parameter rescale math function inThe magnitude of this change not only depends on the load but also on the load power factor. It is also defined as “the rise in voltage when full load is removed divided by the rated terminal voltage when speed and field excitation remains the same.” It is given by the formula, V.R. = ((V NL - V FL) / (V FL)) × 100%. Where, V NL: Voltage ...The efficiency of a 3-phase transmission line can be calculated by using the expression below: Transmission efficiency of a 3-phase transmission line, % ἠ = (Receiving end power/Sending end power)/100. % ἠ = [ (Receiving end power/ (Receiving end power + losses)]/100.
