Elettra - Digital Impulse Acquisition and Analysis System

SHARE
The DIAS, or Digital Impulse Acquisition and Analysis System, is an advanced digital impulse analyzer that is integral to measuring and analyzing impulse voltages and currents in high-voltage systems. Designed with a modular and expandable architecture, the DIAS is suitable for rack or desk mounting in laboratory settings, particularly within impulse test systems' control units. It effectively performs measurements on full and chopped lightning or switching impulse voltages, and is heavily protected against electromagnetic interference common in these tests. Complying with standards such as IEC and IEEE, it can be used in routine and type testing of components like transformers and cables, and supports research and factory testing applications. The system's software facilitates precise analysis of impulse parameters and supports seamless integration with AMETest impulse generators, ensuring efficient tuning and testing.

The Digital Impulse Analysis System “DIAS” is able to perform the following measurement:

  • Measurement of voltage lightning impulses LI
  • Measurement of voltage chopped impulses LIC
  • Measurement of voltage switching impulses SI
  • Measurement of current impulses
  • Calculation and elaboration of impulses parameters

The DIAS is a digital impulse analyzer with a modular and expandable design. It is the brain of the impulse voltage and impulse current measuring system.
The device can be used for measurement and analysis of full and chopped lightning or switching impulse voltages.
- The DIAS system is designed as rack/desk mounting in stationary applications for labs, typically integrated inside the impulse test systems control unit
The DIAS is heavily protected against EMC/EMP that can occur during impulse chopping voltage testing and impulse current testing.
The DIAS is according to standards as IEC 60060-1 and -2, 60044, 60076, 60099, 60694,
61083-1 and -2, 62271, 62475, IEEE and GOST standards.
The evaluation software is already able to perform analysis for impulse test on transformers, cables, bushings, surge arresters.

Main applications are:
Routine and type testing on components as transformers, cables, GIS, bushings, etc. Factory testing
Research, university and reference measurement
Main features are:
Measuring and displaying impulse voltage and current waves and evaluating impulse parameters for peak voltage, current, time, oscillations and over-shoot
Storing csv and processed data for evaluation and comparison of results from different tests
The DIAS is used with HV components as Impulse generators, dividers or shunts from
