Synchroscope
This is the graphic object used in the "
Synchro
" page of the
i4Gen
. It allows, during a synchronization, to
visualize the phase, frequency and voltage differences between the generator and the mains/bus bar as well
as the synchronization conditions.
1.
The position of the white "
ball
" indicates the phase shift (from -180° to 180°) between the generator and
the mains/bus bar. The green area displayed on the phase circle indicates the maximum phase
deviation accepted to allow the circuit breaker to close.
2.
In the bargraphs located in the center of the synchroscope, the cursor position represents the
frequency/voltage difference between the generator and the mains/bus bar. The green area displayed on
each bargraph indicates the maximum frequency/voltage deviation accepted to allow the circuit breaker
to close. If the frequency difference is too high, the cursor become red colored and the phase measure
(ball) is not displayed anymore.
3.
The four dials around the phase circle represent the synchronization conditions. Each dial is:
·
Colored in gray (and its label colored in red) if the condition is not respected.
·
Colored in green (and its label too) if the condition is respected.
