SC9000 EP medium voltage drives IB020001EN—February 2016 www.eaton.com 77
Section 6: High voltage input
Purpose
The SC9000 EP can deliver 2400 V, 3300 V or 4160 V output
voltages, and can accept input voltages between 2.4 kV and
13.8 kV. When the source voltage is above 6.9 kV, the
SC9000 EP must include an additional 72-inch wide cabinet
grouping. This grouping houses a 95 kV BIL incoming line
termination array and a 15 kV input vacuum contactor starter.
The SC9000 EP 24 pulse isolation transformer primary and
secondary windings are also chosen according to the project
input and output voltage requirements.
Contactor
The Ampgard Type SL, 300A, 15 kV vacuum contactor can be
applied at voltages up to 13,800V and is rated to drive up to a
7500 hp induction motor (300 AFL).
