Elspec G5DFR is a multi-functional digital fault recorder equipped with Elspec unique integrated PQZIP technology. The recorder complies with IEC 61850 MMS, GOOSE messaging and sample value, and surpassing IEC 61000-4-30 Class A requirements, the G5DFR continuously records and stores all waveform signals at sampling rate of up to 1,024 samples per cycle thanks to its PQZIP compression algorithm, enabling data analysis at any time. Its synchronization algorithm is based on several sources with an automatic hierarchy for the preferred source availability to assure that logged data from multiple units is synchronized & displayed on the same time scale with typical 1μs resolution.

Reliable root cause analysis, fast troubleshooting and complete power quality visibility

The inventive architecture of Elspec multi-functional recorders takes power quality monitoring to a whole new level. Our meters provide the ability to record the waveform at sampling rate of 1,024 sample/cycle on-board for 1+ years in a continuous way. All our metering and recording solutions are supported by our multi-vendor power management software PQSCADA Sapphire. This combination provides the calculation of more than 5,000 power parameters from the recorded waveform for display and reporting purposes. Guarantee the availability of data for any event at any time.

Advanced capabilities

  • PQZIP inside

Continuous waveform recording

Trigger free setup

5000 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

Elspec’s pioneering measurement method utilises a dual-range gain of 2 x 16 Bit to yield, a superior accuracy far surpassing IEC 61000-4-30 Class A requirements, thereby capturing the finest details & deviations in Power Quality parameters.

  • Synchronized Monitoring

A unique time synchronization algorithm assures that logged data from multiple units is synchronized & displayed on the same time scale with typical 0.1 ms resolution. Every event on a grid is accurately analyzed for precise root cause analysis, behaviour propagation, and traced to its source.

  • Energy Technology List

Approved on the DESNZ energy technology list.  The ETL product approval and qualification for provides independent verification that the Elspec power quality and energy products are in the top 25% of power and energy monitoring test instrumentation currently available on the market.
