The MICRAPAC 925 Remote Terminal Unit
(RTU) is specifically
designed to operate as a completely functioning RTU in a single complete
and compact package. The MICRAPAC 925 provides all SCADA
functions including status monitoring, alarm monitoring, SOE time tagging,
accurate analog measurement from transducerless A.C. inputs, Select-Before-Operate
controls with single point failure protection, and provides full communications
support via a choice of hardware interfaces combined with the selection
of many different data protocols from HAI's library.
For Electric utilities, the MICRAPAC 925 will measure
the full three phase current and voltage values, using HAI's standard
32 samples per cycle technology, and compute all watt, var and phase angle
values as well as current direction, inrush conditions and zero sequence
current. This A.C. metering is combined with status and Select-Before-Operate (SBO) control for full support of Electric Distribution Feeders, Load Management
and Remote Switching Networks.
For Gas utilities, the MICRAPAC 925 when equipped
with the appropriate I/O, can perform several AGA calculations along with
local PID control. The MICRAPAC 925 would typically
perform two AGA 3 calculations using AGA8 or Redlich/Kwong, Wichert Aziz
sour gas corrections providing fast, accurate flow values in a matter of
seconds. Flow values can be stored in set intervals of Monthly, Daily, Hourly
for a period of 35 days. MICRAPAC 925 is also equipped
with 4 status inputs and 4 control outputs.
Further, the MICRAPAC 925 will directly support satellite
time synchronization and low power radio communications. The MICRAPAC
925 is an ideal solution for a compact, easily installed and
maintained unit with flexible and powerful communications support. Additionally,
for substation automation systems the MICRAPAC 925 can
be equipped 1 or 2 8-port Fiber optic modules for communications to multiple MICRAPAC 925
SubRTUs and other IED devices via a Fiber
optic local area network.
The MICRAPAC 925 has the functionality and flexibility
to meet the most demanding SCADA system requirements. Providing Peak
Performance the MICRAPAC 925 is the answer to your
SCADA needs for Distribution and Substation Automation applications in the
Electric & Gas utility industries.
