Power quality analyzer PQI96

Overview

PQI96 is a modern digital measurement instrument, providing accurate three-phase measurements of AC electrical quantities. It also enables power quality assessment according to present standards.

Areas of application

The Power Quality Analyzer PQI96 is intended for continuous measurements of electrical power and power quality parameters in three-phase AC networks. It can be used to control the conformity of power quality with EN50160 norms.

Features

Multifunctionality
Device carries out measurements of harmonics, interharmonics, unbalance, flicker, active, reactive and apparent powers, phase angles of fundamental and harmonic components and much more.

High accuracy and standard compliance
All power quality measurements are made according to IEC 61000-4-30 ed.2 Class A. Harmonic and interharmonic components are measured according to IEC 61000-4-7 Class I. Flicker is measured according to IEC 61000-4-15 Class F3.

Very compact form-factor (96 x 96 x 75 mm)
enables fast and easy installation into distributing panels.

Increased LED indicator height (25 mm)
provides comfortable local meter readings.

Ethernet based synchronization (NTP/PTP)
does not require additional synchronization circuits and is accurate up to ±1µs.

Competitive price
compared to existing power quality instruments.
