LS Series load banks are
used where the genset is too large for the load application.
Consequently, the genset is under loaded. Another example is
when the genset is under intermittent loading such as on building
sites where a transient type load condition may occur on the
genset. Prime power gensets operating during off peak periods
of the day are also subject to under loading. Installation
of an appropriately sized LS type load bank, connected in parallel
with the building load, ensures smooth running and operation
of the genset regardless of the building load condition.
LS Series load banks incorporate the SmartLoad ® LS800D
intelligent load monitoring microprocessor controller. The
controller monitors the building load via a CT located on the
genset alternator busbar and compares the load against a pre
set value determined for the size of the genset. As the building
load falls below the minimum level appropriate for the genset,
step by step load stages are switched in from the load bank
to supplement the building load. The linear hysteresis of the
control, ensures fast response and conditions the building
load accordingly by adding an appropriate load value from the
load bank. Upon recovery of the building load, the processor
sheds load stages from the load bank to correspond with the
controller's set value. The load bank is immediately removed
and undergoes a five minute fan run on period upon recovery
of mains power supply of genset shutdown. |
