Voltage Regulation Vs Power Factor

Let s understand some basics before coming to your question how power factor of any load determines curre.

Voltage regulation vs power factor. Power factor correction and voltage regulation are closely related. Voltage regulation is a measure of change in the voltage magnitude between the sending and receiving end of a component. P vi cosɸ therefore i 1 v for low power factor current will be. What is voltage regulation.

Larger or paralleled conductors to reduce voltage drop under load are in many cases the proper solution. Equation 3 66 implies that voltage regulation is the maximum when the load power factor lagging angle has the same value as the angle of the equivalent impedance. A power factor of less than one means that the voltage and current waveforms are not in phase reducing the instantaneous product of the two waveform. First of all voltage regulation is one of the figure of merits like efficiency from which performance of electrical machines can be judged.

Electric utilities aim to provide service to customers at a specific voltage level for example 220 v or 240 v. Line regulation or input regulation is the degree to which output voltage changes with input supply voltage changes as a ratio of output to input change for example typically 13 mv v or the output voltage change over the entire specified input voltage range for example plus or minus 2 for input voltages between 90 v and 260 v 50 60 hz. Where i is the full load secondary current and v 2 the full load secondary voltage equal to the value of v 2 rated. It is defined as the difference between sending and receiving end voltage per unit sending end voltage.

Voltage regulation vs v r x100 vr thus voltage regulation can be defined as the drop in receiving end voltage from no load to full load expressed as percentage of receiving end voltage for a transmission line it is expected that receiving end and sending end voltage are same. However due to kirchhoff s laws the voltage magnitude and thus the service voltage to customers will in fact vary along the length of a conductor such as a distribution feeder see electric power distribution. Explanation of voltage regulation of transformer. It is commonly used in power engineering to describe the percentage voltage difference between no load and full load voltages distribution lines transmission lines and transformers.

Figure 3 b shows a phasor diagram for the case of an inductive load lagging power factor on the transformer i e the load current lags the secondary voltage by 90 o. This occurs because the transformer is an inductor and follows the laws of physics for inductors. Voltage regulation of transformer at lagging power factor.
