DEIF FAS-115DG Synchronisation & circuit breaker closing
FAS-115DG
Synchronisation & circuit breaker closing
DEIF’s synchronisers are applied for synchronisation of a generator to the busbar and closing of its circuit breaker when the voltage difference, the slip frequency and the phase angles are within the preset limits.
DEIF’s synchronisers are applied for synchronisation of a generator to the busbar and closing of its circuit breaker when the voltage difference, the slip frequency and the phase angles are within the preset limits.
The synchronisers can be applied in conjunction with a wide range of prime movers, as its control pulses may be set to fit several types – from slow reacting dieselengines to fast reacting gas turbines.

The LSU-112DG is equipped with an unload input.
When activated this input will control the power unit to
zero power, and at the same time the power output of
the LSU-112DG is disconnected from the paralleling
line.
The calibration of the LSU-112DG is done so it matches
its power unit. This means that load sharing between
power units with different size will be performed accord
ing to the actual size of the individual power unit in the
plant. For example a 100 kW PU and a 150 kW PU
running in parallel will share a total load of 125 kW into
50 kW and 75k W. If the 150 kW PU is derated to 100
kW by means of the DERATING potentiometer on the
front of the LSU-112DG, the load in the above example
will then be shared equally between the two power
units.
