a maximum peak current that will allow them to close and latch the
mechanism.
High-current conductors are sometimes made with liquid cooling,
one form utilizing copper tubing soldered or brazed into grooves that
are milled into the edge of the bus. An advantage of liquid cooling in
general is that most of the heat generated in the equipment can be
transferred to the water, thus minimizing heating of the air in cabinets
with power electronics. Liquid cooling also saves on copper.
Buswork carrying high levels of AC currents, especially with a high
harmonic content, may cause parasitic heating of adjacent steel cabi-
net parts due to induced eddy currents. One solution to the problem is
to replace the cabinet sections with stainless ...
