Talk:Diversity factor
please give me some more clariffication regarding this. if the MDB diversity factor is considered as .9,then can we take the DBs(which are feeding from MDB) diversity factor as 1? The diversity factor should be always greater than 1.0. Only the Demand Factor is always less than 1.0. You cannot consider the MDB diversity factor as 0.9.
Maximum Demand
As a graduate electrical engineer, I am still struggling to calculate maximum demand of circuits / distribution boards. Could somebody please clarify this confusing topic ?
Example problems would be good, such as a simple 3 phase 50kW motor for example. —Preceding unsigned comment added by 116.212.192.158 (talk) 23:00, 3 March 2010 (UTC)
Issues with IEEE definition
It is worth noting that the IEEE definition is quoted (it looks like verbatim) but is somewhat flawed. First, the term is described as a "probability", but the definition then states that the value is always greater than 1.0, which is clearly not possible for a probability. Second, the contrast with diversity is inapt because diversity is described here as the fractional run-time of a single device (i.e., the duty cycle) rather than the fractional load of an aggregation of devices, which includes other phenomena, such as load coincidence and load state synchronization. Rewriting this will be challenging because the term diversity factor is defined by IEEE in at least two standards and used accordingly by utility engineers, in spite of these problems.
One approach to improving this page is to quote and critique the IEEE definitions and then list the relevant related terms separately with suitable discussion.
