A. Introduction Three phase transformers are used throughout industry to change values of three-phase voltage and current. Since three-phase power is the most common way in which power is produced‚ transmitted‚ and used‚ an understanding of how three phase transformer connections are made is essential. In this section it will discuss different types of three phase transformers connections. A three-phase transformer is constructed by winding three single-phase transformers on a single core. These

other substances and liquids‚ water takes on numerous forms. It can either be solid as ice‚ gas as steam‚ and its usual liquid phase‚ water. Water molecules are electrically neutral and V-shaped with molecular formula H2O. In water‚ each hydrogen atom is bound to the oxygen atom by an electron pair‚ which is shared between them; this is known as covalent bonding. This process only uses two of the six

Saturday‚ December 1st‚ 2012: The moon phase is a Waning Gibbous phase with 93% of the moon illuminated. When the moon is in waning phases the moon is becoming less illuminated each night‚ while gibbous means that the moon is more than 50% illuminated but less than 100%. During this phase the Waning Gibbous moon occurs after the Full Moon and before the Last Quarter. Sunday‚ December 2nd‚ 2012: The moon phase is a Waning Gibbous phase with 87% of the moon illuminated. Compared to yesterday the moon
