Chapter 1 Introduction
10 PowerSmart Socket Power Quality Meter
• High-voltage fast transient recorder; impulsive and low
frequency oscillatory transient overvoltages with peaks up to
2kV and durations from 20 microseconds
• Ready-for-use compliance statistics reports with the
supplementary software
Fault Recorder
• Digital Fault recorder: three voltage and three/four current
channels, up to 10 external digital triggers for monitoring
circuit breakers and protection relays; onboard overcurrent
and undervoltage fault detector; zero-sequence voltage and
current, voltage and current unbalance; programmable fault
thresholds and hysteresis
• Up to 50 Amp fault currents
• Ready-for-use fault reports with the supplementary software -
fault current magnitudes and duration, coincident volt
magnitude, fault waveforms and fast RMS trace
Event Recorder
• Event recorder for logging internal diagnostics events, setpoint
and I/O operations
Waveform Recorders
• Three fast Waveform recorders: up to 7 channels simultaneous
recording of three voltage and three/four current channels
• Fixed and event-controlled recording time
• Selectable sampling rate of 32, 64, 128 or 256 samples per
cycle; 1-20 pre-fault cycles; 0-2048 post-fault cycles in event-
controlled mode; up to 3 min of continuous recording at a rate
of 32 samples per cycle
• Optional 4-channel transient voltage recording at 1024
samples per cycle (with the transient add-on module)
• Synchronized waveforms from multiple devices in a single plot
• Exporting waveforms in COMTRADE and PQDIF file formats
Data Recorders
• Sixteen Data recorders
• Programmable data logs on a periodic basis and on any
internal and external trigger; triggering from the Fault
recorder, PQ recorder or control setpoints; exporting data
trends in PQDIF file format
• Fast fault and PQ data profiling (trending) triggered from the
Fault and PQ recorders: 1/2-cycle to 10-min RMS envelopes;
up to 20 pre-fault and post-fault cycles
Programmable Logical Controller
• Embedded Programmable Controller: 16 control setpoints
• OR/AND logic, extensive triggers, programmable thresholds
and delays, relay control, event-driven data recording
