Live Chat »Q We recently had a problem providing temporary power to numerous pieces of 208V, single-phase equipment of various sizes. Sources of power were a number of 120/208V panels, having different power/current ratings. Some panels were unloaded, some had combinations of loads at 120V, single-phase, 208V, single-phase, and 208V, 3-phase. What is the best and fastest way to calculate the ….

UPDATE: From the comments and answer from Olin and Jason, I've created the following graph showing Watts per foot of $2.5mm^2$ copper wire: But how do I translate this into the the actual temperature rise.

Live Chat »In electrical engineering, Neher-McGrath is a method of estimating the steady-state temperature of electrical power cables for some commonly encountered configurations. By estimating the temperature of the cables, the safe long-term current-carrying capacity of the cables can be calculated. J. H. Neher and M. H. McGrath were two electrical engineers who wrote a paper in about how to.

Live Chat »It is best to obtain the actual load and no-load losses in watts from the transformer manufacturer, but sometimes those data are not available. In that case, temperature rise is a rough indicator of transformer efficiency. For example, a transformer with an 80C temperature rise uses 13-21% less operating energy than a 150C rise unit.
