ISKRA Launches a new Power Quality Analyzer iMC784 used for utility purposesas well as for industrial purposes

ISKRA's POWER QUALITY ANALYZER iMC784 is an important device for permanent monitoring of power quality from its production (especially renewable), transmission, and distribution all the way to the final consumers.

Lack of information about the supplied quality of voltage can lead to unexplained production problems and malfunction or even damage to equipment used in the production process. 

Power Quality Analyzer iMC784 can be used for utility purposes (evaluation against standards) as well as for industrial purposes (monitoring supplied power quality).
 

Power Quality Analyzer iMC784 performs measurements in compliance with regulatory requested standard EN 61000-4-30 Ed.3 and evaluates recorded parameters for analysis according to parameters defined in European power quality standard EN50160.
 

The device enables the storage of a wide variety of highly detailed oscillography data in 8 GB of internal flash memory based on a sophisticated trigger settings mechanism. Data can be stored in standardized PQDIF (IEEE 1159-3) and COMTRADE (IEEE C37.111) file formats which can be easily exchanged with third-party PQ analysis SW systems.

Moreover Power Quality Analyzer iMC784 stores measurements and quality report in internal memory for further analysis. By accessing recorded or real-time values from multiple instruments installed in different locations it is possible to gain the overall picture of the complete systems’ behavior. This can be achieved with regard to Power Quality Analyzer iMC784's accurate internal real-time clock and wide range of synchronization sources support, which assure accurate, time-stamped measurements from dislocated units.

Stored data can then be transferred to a PC or server for post-analysis. The simplest way this is done is by directly connecting a PC with installed MiQEN Setting Studio SW via USB cable.

Features

Evaluation of the electricity supply quality in compliance with EN50160 with automatic report generation.

Class A (0.1%) accuracy in compliance with EN61000-4-30 Ed.3.

Instantaneous evaluation of over 700 electrical measurement quantities values including PQ-related parameters, harmonics (voltage/current THDs, TDDs, up to 63rd voltage(PP, PN)/current harmonics, and interharmonics).

Automatic range selection of 4 current and 4 voltage channels (max. 12.5 A and 1000 VRMS) with 32 kHz sampling rate.

Oscillography capability for recording waveforms and transients with up to 625 samples/cycle sampling frequency.

Recording of waveform, disturbance, trend, and Power Quality (PQ) events in trigger-related recorders.

All trigger-related recorder data is available on-demand through FTP.

A sophisticated triggering mechanism to register and record events of various nature:

Current and voltage transient event generated triggers based on hold-off time (in ms), absolute peak value (% of Un), and fast change (in % Un/μs).

PQ event generated triggers based on the following events: voltage dip, voltage swell, voltage interruption, end of voltage interruption, rapid voltage change, and inrush current.

External Ethernet triggers enabling trigger events with up to 8 different devices within the network.

External digital triggers are based on logical/digital inputs.

Up to 16 combined triggers enabling logical operation on previously configured triggers of various nature.

Recording a wide variety of data in the internal device 8 GB flash memory based on trigger settings:

All activated triggers together with a timestamp, duration, condition as well as a reference to an (optionally) generated transient, waveform, disturbance, and fast trend record.

Waveform recorder with PQDIF/COMTRADE data format selection, selectable recorded channels (4×Voltage, 4×Current, 16×Logical input), 19 samples/cycle to 625 samples/cycle resolution, pre-trigger time from 0.01 s up to 1 s, post-trigger time from 0.01 s up to 40 s (20 s for 625 samples/cycle).

Disturbance recorder with PQDIF/COMTRADE data format selection, selectable recorded channels (4×P-N Voltage, 3×P-P Voltage, 4×Current, 8×Logical inputs), half/full cycle averaging interval, pre-trigger time up to 3000 cycles, post-trigger time up to 60000 cycles.
