Where BESTCOMSPlus® makes it
easy to set relays, BESTspace makes it easy
to configure BESTCOMSPlus and
utliize BESTLogicPlus. The BESTspace tool in
BESTCOMSPlus allows you to clearly
identify relevant settings and adapt them to
your specific application - minimizing
errors and time spent creating settings
files. The files below will assist you in
using Basler Electric preconfigured
BESTspace and preprogrammed
BESTLogicPlus
logic files.
BESTLogicPlus programmable logic
provides the user with a highly flexible and
easy to use visual method of configuring a
protection and control system in the BE1-11
family of products. It comes standard with each
BE1-11 family relay.

Updated! Intertie
Protection - Provides protection
elements to cover all intertie needs defined by
IEEE Standard 1547-2003. The logic scheme is
comprised of two phase, ground and
negative sequence directional instantaneous
overcurrent zones, and two phase and ground, and
one negative sequence directional time
overcurrent zones. Network and conditional
reclosing (25 and 25VM), breaker failure
protection, over/under voltage phase protection,
directional power, and over/under/rate of change
frequency protection are included in
this scheme. This scheme can be used in
conjunction with other Basler Electric products to provide
main-to-main protection. May be used with BE1-11i
and BE1-11g relays.
Feeder Protection
Schemes - BE-11f
Updated! Basic Overcurrent
Protection - Provides basic time and
instantaneous overcurrent protection. Included
protective elements are phase, neutral, and
negative-sequence overcurrent protection.
Functions such as breaker failure, virtual
breaker control, automatic reclosing, and
protective voltage features are not enabled in
this scheme. However, these features may be
activated through BESTLogicPlus.
Updated! Overcurrent Protection with Control
- Similar to Overcurrent Protection
with Reclosing but has the added ability to
manually open and close the breaker by using the
virtual breaker control switch (101). Breaker
failure and voltage protection features are not
included in this scheme. However, these features
may be activated through BESTLogicPlus.
Updated! Overcurrent Protection with Reclosing
- Provides time and both high-set and low-set
instantaneous overcurrent elements for phase,
neutral, and negative-sequence protection.
Automatic reclosing is included and initiated (RI) by a
protective trip or by an external reclose
initiate contact. Breaker failure, virtual
breaker control, and protective voltage features
are not activated in this scheme. However, these
features may be activated through BESTLogicPlus.
Updated! Feeder Protection
with Interlock - Provides time and both
high-set and low-set instantaneous overcurrent
elements for phase, neutral and
negative-sequence protection. Automatic
reclosing is included and initiated (RI) by a
protective trip. The breaker may be manually
opened or closed via the virtual breaker control
switch (101). Protective voltage features are
not enabled in this scheme. However, these
features may be activated through BESTLogicPlus.
Interlock logic allows for bus overcurrent
backup of feeder relays and allows for fast bus
overcurrent protection.
Updated! Primary Bus Overcurrent Protection
- Applies to a bus main relay to provide
primary bus overcurrent protection. Contains
logic to interconnect with the Feeder Protection
with Interlock logic scheme to provide
high-speed overcurrent protection for the bus
under normal conditions. It also contains logic
to trip the feeder breakers while the feeder
relays using the Feeder Protection with
Interlock logic scheme are out of service.
Updated! Backup Bus
Overcurrent Protection - Apply to a bus main relay
to provide backup bus overcurrent protection as
well as breaker failure protection for the bus
breaker under normal conditions. Also
provides primary bus overcurrent protection when
the relay using the Primary Bus Overcurrent
Protection logic scheme is providing feeder
protection or when the primary bus relay is out
of service.
Generator Protection Schemes - BE1-11g
Updated! Basic Low Impedance Grounded Generator
Protection - Provides
basic protection of generators grounded
through a low to moderate neutral impedance.
The simple and straightforward tripping scheme provides
for three tripping outputs using the same logic
for all three outputs. Tripping

Updated! Basic High Impedance Grounded Generator
Protection - Provides
basic protection of generators grounded through
a high neutral impedance. The simple and
straightforward tripping scheme provides
for three tripping outputs with the same logic
being used for all three outputs. Tripping

harmonic), two 32 Reverse Power, 40Q, 40Z, 46,
47, 50P/50N Inadvertent Energizing, 51 Phase

Updated! Low Impedance Grounded Generator
Protection with Sequential Trip -
Provides for more elaborate protection for
generators grounded through a low to moderate

one each for main breaker, field, and prime
mover tripping, with different logic for each.
