Figure 2-3. This subsection describes the Switchgear Regulator Style
Powerpack. The SGRS Powerpack operates similar to the stand-alone type
L-828 / L-829 and uses a URC to provide regulator and control functions.
It also uses the Advanced Control Equipment (ACE or ACE2) for
control and monitoring functions.
The main difference is the CCR frame which is designed to insert into a
SGRS line-up.
NOTE:
Figure 2-3 shows a ferroresonant L-829 (30 kW/6.6 A) CCR. The other L-
829 CCRs (4, 7.5, 10, 15, 20 kW/6.6 A/20 A and 50/70kW) may differ in
size and appearance.
