12.1.4 Line reactors
Input line reactors reduce the risk of damage to the drive resulting from
poor phase balance or severe disturbances on the supply network.
Where line reactors are to be used, reactance values of approximately
2% are recommended. Higher values may be used if necessary, but may
result in a loss of drive output (reduced torque at high speed) because of
the voltage drop.
For all drive ratings, 2% line reactors permit drives to be used with a
supply unbalance of up to 3.5% negative phase sequence (equivalent to
5% voltage imbalance between phases).
Severe disturbances may be caused by the following factors, for example:
•
Power factor correction equipment connected close to the drive.
•
Large DC drives having no or inadequate line reactors connected to
the supply.
•
Across the line (DOL) started motor(s) connected to the supply such
that when any of these motors are started, the voltage dip exceeds
20%
Such disturbances may cause excessive peak currents to flow in the
input power circuit of the drive. This may cause nuisance tripping, or in
extreme cases, failure of the drive.
Drives of low power rating may also be susceptible to disturbance when
connected to supplies with a high rated capacity.
Line reactors are particularly recommended for use with the following
drive models when one of the above factors exists, or when the supply
capacity exceeds 175kVA:
BA
1201 BA1202 BA1203 BA1204
BA
1401 BA1402 BA1403 BA1404
Model sizes BA1405 to BA4606 have an internal DC choke and BA5201
to BA6602 have internal AC line chokes, so they do not require AC line
reactors except for cases of excessive phase unbalance or extreme
supply conditions.
When required each drive must have its own reactor(s). Three individual
reactors or a single three-phase reactor should be used.
Reactor current ratings
The current rating of the line reactors should be as follows:
Continuous current rating:
Not less than the continuous input current rating of the drive.
Repetitive peak current rating:
Not less than twice the continuous input current rating of the drive.
