HVEX Software: Enhancing Transformer Testing
Discover how HVEX is transforming the way transformer testing is conducted. With its innovative solutions and cutting-edge technology, HVEX offers significant improvements in terms of efficiency and quality in this crucial process.
1. HVEX LIAS
LIAS, short for "Lightning Impulse Analysis System," is software used for analyzing atmospheric voltage and current impulse tests. It is 100% original, developed exclusively by HVEX for the analysis of atmospheric voltage and current impulse tests.
Data Storage and Organization: Centralize all essential information
HVEX LIAS stores data about clients, manufacturers, transformers, oscilloscopes, and other test-related equipment. It allows parameterizing, controlling, and recording all aspects of the test, offering a user-friendly interface and automatically generating customized reports in .pdf and .doc formats.
Parameterization and Control: Customize your tests
The software is used in testing laboratories that conduct voltage or current impulse tests. To use it, the software must be installed on a computer and establish communication with the laboratory. The user must register the client, the laboratory, parameterize the PLC and the oscilloscope, and indicate the relevant voltage or current levels for the test.
Precise Recording: Document every step of the test
LIAS plays a fundamental role in the safety and reliability of tests conducted in laboratories. The software allows the registration of equipment, ensuring compliance with the voltages and currents applied to established standards. Additionally, LIAS monitors the voltage level and safety mechanisms, preventing access to energized parts during the test.
With its automated analysis, LIAS streamlines test execution. Report generation and the ability to export collected data allow effective control of results. LIAS is an essential tool for analyzing impulse tests in transformers, contributing to obtaining accurate and reliable results.
2. HVEX PDMS
What is PDMS?
HVEX PDMS is a dedicated supervisory software used to trigger and control tests, filter reading signals for noise removal, manage the database, and visualize application results through a graphical interface. PDMS stands for "Partial Discharge Monitoring System." The software is intuitive, has a user-friendly interface, and allows automatic generation of customized reports in .pdf and .doc formats.
The functionality behind PDMS
PDMS is used in testing laboratories that monitor partial discharges (PDs) or high-frequency signals, such as partial discharges meters and radio interference voltage testing laboratories. To use PDMS, the user must have a computer with the software installed and establish communication with the laboratory to be controlled. To perform the tests, the user must register the client for whom the test is being performed, the equipment to be tested, and the oscilloscope communication parameters. Additionally, gain and gate levels, filter information, and cutoff frequencies must be indicated.
These settings are important to ensure that the read signal is indeed a PD and that the reading is accurate.
The software revolutionizing partial discharge measurements:
PDMS allows calibration of the measurement system to ensure that the high-frequency signals read are indeed partial discharges, recognizing the noise level present in the measurement environment and making the necessary corrections for partial discharge calculations. Additionally, PDMS allows analysis in both time and frequency domains, indicating the concentrations of partial discharges occurrences on a color map to make levels intuitive and visible. It can also perform analysis of radio interference voltage as a function of signal frequency. The software automatically presents the number of partial discharges occurrences, the average charge in pC, and the maximum discharge, both positive and negative.
