Description
Elspec G5 Multi Function Digital Fault Recorder
The Elspec BlackBox G5DFR is a fully featured digital fault recorder equipped with PQZIP technology. The Elspec G5DFR is a distributed multi-functional data acquisition device that continuously records all waveform signals at sampling rate of 1,024 samples per cycle.
PQZIP inside
- Continuous waveform recording
- Trigger free setup
- 5,000 power parameters @ 1/2 cycle resolution
- Easy deployment
Class A
Far surpassing the highest standards set by the industry, the BLACKBOX device series complies with standards for: aggregations, time clock uncertainty, flagging, and transient influence quantities.
Superior Accuracy
The Elspec G5DFR is equipped with 24 bit ADC to yield, a superior accuracy far surpassing IEC 61000-4-30 Class A requirements, thereby capturing the finest details & deviations in PQ parameters.
Synchronized Monitoring
The BlackBox DFR’s synchronization algorithm is based on several sources with an automatic hierarchy for the preferred source availability (accuracy based hierarchy). This unique time synchronization algorithm assures that logged data from multiple units is synchronized & displayed on the same time scale with typical 1 μs resolution.
Multi Functional Recorder
- Digital Fault Recorder (DFR)
- Phasor Measurement Unit (PMU)
- Power Quality Monitoring (PQM)
- Sequence of Event Recording (SER)
- Dynamic System Monitoring (DSM)
- Impedance based Fault Location (IbFL)
- Energy Billing Measurement (EBM)
- Impedance Distance to Fault Location (IDFL)
Continuous Waveform Recordings
The G5DFR is a multi-functional recorder able to record and store all electrical waveform at any given time, for more than a year, with no gaps in the data. RMS, harmonics and any other values from waveform in post-processing are calculated, including the tabulation of more than 10,000 parameters.
Supreme Trends Resolution
The G5DFR measures and records 5,000 power parameters continuously at a resolution of ½ cycles, 10/12 cycles, 150/180 cycles, 10 min and 2 hours of which, any given resolution is calculated for display and reporting purposes. Hence, there is no need to select which parameters to log, and more importantly, which parameters to ignore.
Harmonics & Inter-Harmonics Analysis
The G5DFR power quality analyser boosts two FFT engines for harmonics analysis: Cycle by Cycle: performs FFT at 1 cycle resolution for extended bandwidth. This engine provides 512 harmonics order at 50Hz resolution. 10/12 Cycles: performs FFT 10/12 cycles resolution for extended resolution and sub-grouping calculation. This engine provides the magnitude and angle of 512 spectrum components at 5Hz resolution.
Comprehensive Event Mechanism
The G5DFR analyser is designed to detect any event occurring on your system. The event mechanism allows you to configure events on any measured parameter (more than 1,000) and/or I/O ports. The event mechanism supports out-of-limit events as well as rate of changed limits. The G5DFR records the waveform signals continuously. The event configuration doesn’t trigger the recording but rather stores summary logs including start and end time, duration, severity and magnitude of the event. All events are displayed in a tabular or scatter charts as CBEME/ITIC.
Phasor Measurement Unit
- Complies with the most updated standard for synchrophasor measurements of power systems IEEE C37.118-2011, including the amendment IEEE C37.118.1a-2014. IEC/IEEE 60255-118-1-2018 Certified.
- Two independent synchrophasor data streams enable to report a synchrophasor data with two different report-rates and/or different performance classes (P/M) and/or data type simultaneously.
- Ultra-fast report rate for both P & M classes:
- P 200/sec @ 50Hz 240/sec @60Hz
- M 100/sec @ 50Hz 120/sec @60Hz
- Support for simultaneous synchrophasor data stream over TCP/IP and UDP/IP. It can be configured for unicast or multicast, enabling a better design of WAMS communication and suitable for WAMS with several utilities or applications involved.
