Is the belt interchangeable between a 1991 Pontiac Bonneville and a 88 delta royal?
The tensioner belt is interchangable as both vehicles use the same engine, the GM 3800
The delta is located in southeast Louisiana, with offshore barrier islands that extend south of the state of Mississippi in the Gulf of Mexico. * While the Mississippi River Delta exists in lower Louisiana, there is also another area in the northwest of Mississippi that is called the Mississippi Delta that exists between the Yazoo and the Mississippi Rivers. They are about 300 miles apart and only the Mississippi River Delta is a genuine delta.
For the same load, delta provides higher current than wye, or star. Wye voltage is 1 / 1.732, or 0.577 that of delta. (1.732 is the square root of 3.) This gives a power of 0.333 for wye, as opposed to delta. (0.5772 = 0.333) This is why (no pun intended) we use wye-delta starters on large motors - it allows them to come up to speed at 1/3 power, before switching to full power…
There is no difference. A three-phase 'star' connection is simply another name for a 'wye' connection. 'Star' seems to be the preferred name in Britain, whereas, 'wye' seems to be the preferred name in North America -although this is debatable. Out of interest, the alternative name for for a 'delta' winding is a 'mesh' winding.
In delta to delta there will be no ground on both primary and secondary sides. Leave the primary side but we take care on secondary side. If there any fault occurs on the secondary then there will be unbalanced voltages between the phases results in the flow of current through the secondary windings so only we are using star on the secondary side while having neutral to prevent such a current flow.
