Explanation of three-phase generating set:
(1) Connect the loads to the generating set in order. As for the motor loads, start
the higher power motor first, and then start the lower after the former started. Be
sure not start them simultaneously. Any improper operation arouse, the
generating set will run sluggishly or halt, at this time, be sue to remove the loads
immediately and shut off the motor. Check whether overload happened or any
other faults. If overload made AC air breaker tripped, decrease the loads for
overload is not allowed. Wait some minutes before restart the generating set,
furthermore, do stop the set and make checks if any faults or abnormal
phenomenon still existed.
(2) If both of motor loads and inductive loads (e.g. Incandescent) are connected
to the generating set, first start motor loads and then inductive loads, otherwise,
starting motor loads will be difficult.
(3) Pay more attention to voltage of three phases while running. If the imbalance
of voltage of three phases exceeds 10%, do stop the set and make checks, and
then readjust three phase loads. Keep three phase loads in balance, the
imbalance cannot exceeds 20%. Meanwhile, the total load cannot exceeds rated
load, even the load of each phase cannot exceeds rated phase load, that is 1/3 of
rated load. Furthermore, the current of each phase cannot over rated current.
The sequence of output terminalsA,B,C,O(or U,V,W,N) of three-phase generating
set is from left to right or clockwise direction.
