Elspec power quality analyzers take power quality monitoring to a new level. Equipped with Elspec revolutionary PQZIP compression patent algorithm, our power quality analyzer series enables you to measure, store and analyze waveform signals continually at sampling rate of up to 1,024 samples per cycle. This ensures data availability without the need to set any trigger or threshold, providing unlimited pre & post trigger. Our analyzers far surpassing the highest Industry standards, complying with IEC 61000-4-30 Class A.

Elspec multi-functional digital fault recorder are equipped with the Elspec unique integrated PQZIP technology. They comply 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.

The Equalizer RT is a real-time high performance power quality solution designed to deliver substantial reactive power even during a Fault Ride Through (FRT) or Voltage Ride Though (VRT) event where a very deep voltage sag occurs.  The fault ride through solution has been modified in order to boost supplied kVAr capacity for short time during these voltage dips and has an ultra fast acquisition time and can fully compensate for the voltage sag within less than 10 milliseconds.  This modification makes a transient free connection of capacitors in a Voltage Control operation mode and is optimised to fulfil the PO12.3 Grid Code requirements.
