The
SATEC ezPACTM
SA300 Series Power Intelligence Unit is an advanced power
analysis and control device unmatched in the utility and
industrial environments.
The SATEC ezPACTM
SA300 Series are a fusion of many intelligent electronic
devices (IED) combined into one single powerful unit. The SATEC ezPACTM
SA300 Series unite Distributed Fault-Recording, Sequence of
Events (SOE), Revenue Metering, Power Quality, Back up to
Protection equipment and control devices to provide a complete
solution for substation and industrial automation.
The unique modular expansion chassis of the SATEC ezPACTM
SA300 Series assures the capability of meeting the needs of
today and the future by selecting different plug-in options for
multiple applications. The ezPACTM
allows a relatively low cost upgrade to be accomplished with
just minimal panel and wiring changes. Modular I/O design lets
you order a custom-made product according to your needs.
Upgradeable
Firmware
The SATEC SA300 uses flash memory for storing device
firmware that allows future upgrading of the device without
replacing any hardware component. You no longer have to replace
EPROM and remove from service. The new features can be easily
added to your device by simply replacing the firmware through a
local RS-232 port or Ethernet port.
Substation Automation Upgrade
The SATEC ezPACTM
SA300 Power Intelligence Unit is an ideal cost effective means
of automating an electrical substation. The SATEC ezPACTM
can be installed at a fraction of the cost and time involved in
replacing protection relays.
By adding one SATEC ezPACTM
Model on each feeder circuit, ALL the information needed for
substation automation is provided. The SATEC ezPACTM
SA300 extends the life expectancy of electromechanical relays
for many years to come by providing “INFORMATION”
lacking in these highly reliable devices without interfering in
the protection scheme.
The
SA300 combines in a single enclosure:
|
|
|
Distributed
Fault Recording – Functions
include true digital fault recording, sequence of event
recording, and disturbance recording of four current channels for
up to 150 Amps of fault currents (30X). Four AC voltage channels
and DC measurement input channels are also included. Multiple ezPACTM
can cross trigger for up to 20 cycles of pre-fault information
for distributed recording. Fault information can be exported to
optional COMTRADE format via PAS software.

|
|
Precise
Sequence-of-Events Recorder (SOE) - Designed
for a electrical utility substation or plant environment to
record contact openings and closing of field devices such as
electromechanical and microprocessor controlled relays.16
digital inputs are provided and can easily expand up to a total
of 48 digital inputs (wet or dry type) with a 1 mSec time
resolution between events.
|
|
|
Power
Quality Analyzer - Advanced
power quality monitoring reporting as per IEEE 1159
classification. Report by exception with programmable thresholds
and hysteresis, ready-for-use reports; transients, impulses,
sags/swells, interruptions, inter-harmonics as per IEEE519,
frequency variations, volts unbalance.
|
|
|
High
Speed Sampling- The
utilization of the latest DSP technology and the innovative data
concept allow very long recording periods without compromising
the high level of accuracy. Simultaneous
sampling with individual A/D conversions assures no phase
differential for 12-channels of AC, one VDC and digital inputs
recording. Selectable simultaneous AC recording rate of 32, 64
and 128 samples per cycle; over 3 min of continuous recording
with a 5-Mbyte onboard expandable memory.
|
|
|
Long
Term Recording - For
data logging & trending, internal diagnostics events,
control events and I/O operations.
|
|
|
Fast
Data Logging Recorder - From
1/2 cycle RMS to 2-hour RMS envelopes are provided. Most useful
in quickly determining relay operation by recording the RMS
value of each cycle and displaying the entire trend when breaker
clears, resets, lockout or fails to operate; up to 20 pre-fault
cycles; programmable post fault on any internal and external
trigger condition.
|
|
|
Programmable
Controller – Advanced
programmable logic makes it ideal for controlling multiple CAP
banks, Tap changes under load and alarming. Programmable 32
setpoints control, OR/AND logic, operate with release triggers,
thresholds with delays, relay control, event-driven data
recording.
|
|
|
Digital
Power Meter - You
can now eliminate the added cost of a multifunction digital
meter. Protection relays are poor substitutes for metering and
can be dangerous and misleading when high harmonic contents are
present in AC current or voltages typically found in
distribution circuits. Providing high accuracy True RMS values
for volts, amps, powers, power factors, unbalance, harmonic,
demands (predicted, fixed and sliding) and neutral current are
included.
