SEL-487V Relay
Capacitor Bank Protection,
Automation, and Control
Major Features and Benefits
The SEL-487V Capacitor Bank Protection, Automation,
and Control System integrates voltage or reactive power
control for grounded and ungrounded capacitor banks
with full automation and protection in one device.
➤
Protects Grounded and Ungrounded Banks.
The SEL-487V provides sensitive voltage differen-
tial or current unbalance protection with compen-
sation adjustment. The compensation adjustment is
used to zero out small unbalances that are natural
in the bank as well as instrument transformer
errors. Instantaneous and time-overcurrent ele-
ments and voltage elements provide additional pro-
tection for the capacitor bank. The SEL-487V
provides breaker failure protection for the capaci-
tor bank breaker using high-speed (less than one
cycle) open-pole detection logic that reduces coor-
dination times for critical breaker failure applica-
tions.
➤
Control. The SEL-487V-1 is available with control
functions for maintaining system voltage, VAR or
power factor (PF) levels, and reactor loading. The
control
functions
Schweitzer Engineering Laboratories, Inc.
include
auto/manual
and
local/remote control capabilities with control insta-
bility detection for alarm or blocking of control
operations. Implement the time-of-day control fea-
ture to synchronize capacitor bank insertion with
peak VAR demand periods for any weekday or
weekend period. Automatically sequence as many
as three capacitor bank stages by using the univer-
sal sequencing control. This control provides
sequencing based upon accumulated operating
time, an analog quantity, or a fixed order.
➤
Automation. Take advantage of enhanced automa-
tion features that include 32 programmable ele-
ments for local control, remote control, protection
latching, and automation latching. Local metering
and control on the large format front-panel liquid
crystal display eliminates the need for separate
panel meters and switches. Serial and Ethernet
links efficiently transmit key information, includ-
ing:
➢
Metering data
➢
Protection element and control I/O status
➢
IEEE C37.118 synchrophasors
