Range features
A high level overview of what this range offers
Power Quality Analysers
Elspec power quality analysers all equipped with the revolutionary PQZIP patent algorithm for continuous waveform recording to ensure data availability for any event in the grid without the need to set any triggers or thresholds 3 models are available to meet the user’s needs and requirements for nearly any business and/or application. All models coupled with Elspec PQSCADA Sapphire, a multi-vendors support power management software. When coupled with PQSCADA Sapphire, ~5,000 power parameters at any given resolution are calculated for displaying and reporting purposes from the acquired waveform signals
