Air Cooled
High Current DC Shunt
The Type
2276 High Current DC Shunt range of shunts are specially designed for use up to 20,000
Amperes and maybe used on a steady D.C. load or for pulse work.
Limit of Error
Under steady condition the Type 2276 shunts keep within 0.1% up to
full rated current but this figure is greatly improved if forced air
is used for cooling.

Current
Shunt stability
The
stability of these shunts under steady conditions is 0.01% or better. A typical figure, 20000 Ampere shunt was found to be better than
0.005%.
Compensation
for Phase Angle Errors
When used
for pulse work, the mutual inductance between the potential leads and
the current path in the shunt can be set to compensate for the phase
angle between the current in the shunt and the voltage between the
potential points.
|
The self
inductance of the current through the shunt depends on the arrangement
of the bus bars.
If the return bus bar is made to follow the contours
of the shunt and is kept close to it,
the value can be kept to 0.01mH
or less.

High Current DC Shunt
Construction
The
construction of the Type 2276 High Current DC Shunts are similar to the Type 4638 but
they are usually supplied in a steel lifting frame to facilitate
transporting them without distortion.
They are not supplied on a
base nor fitted with a protecting cover.
