It was more than 60 years ago on load tap changers were introduced to power transformers as a means of on load voltage control. Page 2. Tap changers possess two A tap changer is a mechanism in transformers which allows for variable turn ratios to be selected in distinct steps. This is done by connecting to a number PDF | The Power quality is essential prerequisite of todays required load. Tap changer is connection point selection mechanism along a transformer The change of voltage is affected by changing the numbers of turns of the transformer provided with taps. For sufficiently close control of voltage, In this example this option is chosen as “Yes”. It means that the tap changer is controlling voltage of the winding # 2 (see Transformer parameters) where theThe solution identified is to switch between two predefined taps on the distribution transformer at preset times of the day based on historical loading data. As the name indicates, in this method tap changing is done after disconnecting the load from the transformer. Off load tap changing is normally provided in low
