Power panel configuration and requirements

Minimum requirements:

⁄ Circuit breaker 3 pole (draw out type for MV) with motor drive (24VDC), suitable for

synchronizing and BLACK OUT Start with de excited alternator (No alternator voltage is available)
⁄ 24 (110) VDC closing coil, closing time max. 70 msec. from INNIO Jenbacher interface until

contacts of the generator C.B. are closed, transmission time for the STATUS feedback signal max.
30msec.

⁄ 24 (110) VDC shunt trip coil; trip time max. 60 msec. from INNIO Jenbacher interface until

contacts of the generator C.B. are opened, transmission time for the STATUS feedback signal
max. 30msec.

⁄ 24 (110) VDC under voltage trip coil

• On | Off command from INNIO Jenbacher synchronizing only: Continuous contacts (1 NO and 1 NC) with 24
VDC, 10 A (110VDC, 0,5A) load rating.

• Over current and short circuit protection with primary or secondary relays.

• Current Transformer and Voltage transformer (Project specific)

• Generator transient over voltage surge protection according TA-Nr. 1100-0112
