BE1-11g

APPLICATIONS
The BE1-11g Generator Protection System provides the three phase, ground, and negative sequence overcurrent,
voltage, over/under or rate-of-change of frequency, directional power, loss of excitation, overexcitation, and sync
check functions for use in generator protection applications. The unit also may be used in any directional or
nondirectional overcurrent application that requires frequency and overexcitation protection and that does not also
require a reclosing function. The specialized capabilities of this protective system make it ideally suited for these
applications:
• Applications that require the flexibility provided by wide setting ranges, a large number of elements, multiple
setting groups, multiple coordination curves, and the versatility of visual programmable logic, in a single com-
pact package.
• Applications that require an economic unit with a space-conscious package. The 11g can provide all of the
protection, control, instrumentation, and communications required in many installations.
• Applications where small size and limited behind-panel projection facilities are required to modernize an existing
installation.
• Applications that require high speed Ethernet communications, copper or fiber.
• Applications where drawout construction is required.
