ELSPEC G5DFR

Multi-Functional Digital Fault Recorder

The BlackBox G5DFR is a fully featured digital fault recorder embedded with PQZIP technology. The G5DFR  is a distributed multi-functional data acquisition device that continuously records all waveform signals at sampling rate of 1,024 samples per cycle

Continuous waveform recording

Continuous waveform recording Trigger free setup 5,000 power parameters @ 1/2 cycle resolution Easy deployment

Class A device

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 G5DFR is equiped 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.

Plug & Play

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.

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 analyzer 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 analyzer 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.

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:

Performance ClassMax report rate for 50HzMax report rate for 60Hz
P200/sec240/sec
M100/sec120/sec

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.
