SPEAR single-phase recloser system
description
Recloser description
The SPEAR single-phase recloser consists of an interrupting
module, with an embedded current transformer, and
mechanism mounted to an aluminum head casting. The
mechanism and interrupter assembly are mounted to a
steel tank suitable for pole or substation mounting. The
interrupter module utilizes an outdoor cycloaliphatic-epoxy-
encapsulated vacuum interrupter.
The SPEAR single-phase recloser requires a SPEAR single-
phase recloser control.
Control description
The SPEAR single-phase recloser control includes extensive
system protection functionality.
Analysis tools include sequence of events recording and
data profiler.
Metering functions include demand and instantaneous
current, instantaneous voltage and power factor, and power
(real, reactive, apparent). System frequency is displayed
along with kilowatt-hours for energy metering.
The front panel LCD display is used to configure the
operating settings for the control. It is also used to display
metering, counter information, control parameters, alarms,
and sequence of events.
Control parameters can also be programmed via a personal
computer connected to the control through the front panel
USB port or through the communication board. Control
programming, interrogation, and operations are performed
with SPEAR single-phase recloser control ProView NXG
interface software on a computer.
ProView NXG interface program software includes additional
functions such as configurable sequence of events and
alarm data, and selectable communication points for serial
(DNP3) communication.
The control operates on 50 and 60 Hz systems.
