ezPAC TM Features
The ezPAC TM SA300 Series intelligent electronic devices (IED) are combined fault-
recording, metering and control devices that provide a complete solution for
substation and industrial automation. They incorporate a unique collection of features
commonly found in numerous specialized measurement and recording equipment
utilized in substation and industrial environments. Although the devices are primarily
designed as an inexpensive add-on to expand the capabilities of the existing
substation protection equipment, they are well suited for a wide range of industrial
applications with high input currents whenever extensive power quality monitoring is
required. The SA300 combines in a single enclosure:
• Fast Digital Fault recorder: up to 48 external digital triggers from
protection relays; onboard fault detector; programmable fault
thresholds and hysteresis; up to 150 Amp fault currents, zero-
sequence currents and volts, current and voltage unbalance; ready-
for-use fault reports - fault current magnitudes and duration,
coincident volt magnitude, fault waveforms and fast RMS trace; cross
triggering between multiple devices via digital inputs for synchronous
fault capture and recording.
• Sequence-of-Events recorder: up to 48 digital inputs at 1-ms
resolution, fault events and relay operations.
• IEEE 1159 Power Quality recorder: onboard power quality analyzer;
programmable thresholds and hysteresis; IEEE 1159 PQ event log;
ready-for-use reports; impulsive transients, sags/swells, interruptions,
harmonics, interharmonics, frequency variation, voltage unbalance,
optional IEC 61000-4-15 flicker.
