Products with 3-Phase Inputs
Some of the higher power products exceed the capability
of a single phase line. Agilent offers several power products
which require 3-phase inputs, including the 5KW 668XA
dc source family, the 6814B and 6834B ac Sources. For
3-phase power distribution up to the building, there are
two different distribution systems in wide use: delta, predomi-
nantly used in the US; and wye predominantly used in Europe.
However, for service inside the building, the 5 wire wye is the
predominant configuration. Products which are delta loads,
are compatible with either delta or wye.
As shown in table 4, the delta has only three current
carrying conductors; there is no neutral. The wye configura-
tion has four current carrying conductors. In general, the
neutral should carry no significant current. None of the
Agilent power products use the neutral connection found
on wye systems. Do not connect the neutral to ground.
In selecting the correct operating voltage for 3-phase
products you need to distinguish between the line-to-line
and the line-to-neutral voltages. The line-to-line voltage is
the square root of 3 x the line-to-neutral voltage. It is the
line-to-line voltage that is used to specify the input voltage
to be applied to Agilent power products. For example,
common 3-phase voltages and available options are shown
in table 4.
All Agilent 3-phase power products are shipped with either
a North American or harmonized unterminated line cord
based on the destination country on the purchase order.
