Monitoring made easy

• Trend: The trend graph shows the variations of the parameters measured over time as fast as 200 ms
• Alarms: Alarms set points can be programmed to be monitored, which are then recorded and time-stamped with the duration and extreme values; users can be informed directly by email when an alarm is triggered
• Transients: Transients correspond to peaks in the voltage or current waveform; shockwaves are extremely fast transients with even greater possible amplitude
• True InRush: For tests when starting up loads, it can record ½-period values covering more than 30 minutes and the waveforms of the signal can be captured

Versatile communication

In addition to using media such as SD cards and USB drivers, it is possible to download the measurements and communicate with this instrument remotely via USB, remote links, Wi-Fi (direct or via server), or the RJ45 (Ethernet connector).

The web server

This analyzer is equipped with firmware for remote access. It can be controlled via VNC, which controls a remote machine while displaying its desktop. It can be activated from any browser (Chrome, Edge, Firefox, etc.).

IRD server

The IT networks are protected against external attacks. Thanks to the provision of access to the IRD server, a single authorized IP output address allows you to transmit your measurements all over the world.

SCPI commands

With an integrated interfacing software layer, it is possible to control this instrument via its own software application. SCPI commands are available for all the instrument's functions.

Data files in JSON format

Saved in JSON format, all the recordings are accessible and can be processed with a third-party and/or proprietary application.

Meeting standards

IEC 61000-4-30

The International Electrotechnical Commission (IEC) IEC 61000-4-30 Edition 3.1 standard. This standard defines:

• The methods for measuring the quality parameters for the supply of power to electrical power networks
• How to interpret the results

The measurement parameters are described for each applicable parameter in terms that provide reliable, repeatable results, however the method is implemented.

EN 50160: Homogeneous tolerances

The EN 50160 standard characterizes the quality of the voltage supplied. It presents the different types of disturbances which may affect the voltage on a network. It lists the parameters to be monitored and defines how long the parameters should be monitored for. With the DataView® software, the Monitoring mode can be used to set up a simplified configuration of all the limits to be monitored and the parameters to be recorded.

IEC 61000-4-7: Harmonics and interharmonics

The IEC 61000-4-7 standard defines the measurement methods for voltage quality analyzers so that they remain compliant with the emission levels stipulated in certain standards (e.g. the harmonic current limits specified by IEC 61000-3-2) and for the measurement of harmonic currents and voltages on the power networks themselves.

IEC 61000-4-15: Short or long-term flicker

This is caused by the power supply voltage modulation. When it affects lighting, it gives an impression of unstable vision due to a light stimulus whose luminance or spectral distribution fluctuates over time. There are two parameters calculated from the power supply voltage.

• P_st which is a short-term assessment based on a 10-minute observation period
• P_lt which is a long-term assessment, usually over a period of two hours

DataView data analysis and reporting software

The DataView® software provides a convenient way to configure and control power analysis tests from a computer. Through the use of clear and easy-to-use tabbed dialog boxes, all functions can be configured and tests can be initiated. Results can be displayed in real-time and stored on a PC. Reports may be printed along with the operator's comments and analysis.

Configure all functions of this analyzer

• Display and analyze real-time data on a PC
• Configure all PowerPad functions and parameters from your PC
• Record trend data directly to the PC
• Customize views, templates, and reports to meet specific needs
• Create and store a complete library of configurations that can be uploaded to this unit as needed
• Zoom in and out and pan through sections of the graph to analyze the data
• Display waveforms, trend graphs, harmonic spectrums, text summaries, transients, event logs and stored alarms
• Print reports using standard or user-designed custom templates
• Selectively review individual channels, phases on total network recordings
• Keep track of accumulated energy over time and time of use
• Create user-specific cover sheets for reports identifying specific data that includes operator, tests site and narrative associated with the data

The DataView® control panel

The monitoring feature allows the user to set up a recording with selected parameters for which specific user-defined pass/fail criteria can be applied. The objective is to set up a measurement chart of relevant parameters and monitor them to establish whether an electrical network of source and loads is within control limits. Monitoring can also be set up without any thresholds for pass/fail criteria. The software structure of the setup is flexible and allows the user full customization. The progress of the measurement setup can be viewed in real-time as the measurement is progressing. A customized report can automatically be generated at the end of the monitoring session. Additionally, the control panel makes it easy to:

• Name the Monitoring
• Select Aggregation period from 0.2 seconds to 2 hours
• Schedule Monitoring by selecting Start and Stop Date/Time
• Load Parameters from a file
• Save all the Parameters to re-load later
• Edit Power Ratios
• Add to the Parameter list
• Edit conditions for any Parameter
• Delete a given Parameter from the list
• Monitor an active recording session or a saved session
• Reverse current probes that were incorrectly installed

Applications

Commercial and industrial sectors

Today, electrical distribution networks are judged according to their ability to power loads causing disturbances and loads sensitive to disturbances. The latter may take multiple forms. Voltage quality analyzers can be used to detect and qualify each disturbance type: outage, voltage surges, and sags, flicker, THD, voltage variations, transients, etc.

Energy efficiency

For energy diagnostics on a site, a logger must be set up to record the electrical power and energy consumed. Once all the measurements have been taken, billing data is compared with the actual measurements to determine whether corrective action needs to be taken. This action may take different forms: resizing a transformer, implementing filtering systems, replacement of faulty equipment, etc. This analysis helps you understand and act at the right place and time to provide the best solution.

Electrical maintenance

The increase in electronic power supplies in industrial processes has led to increases in harmonic disturbances on electrical networks which have a direct impact on the quality of energy distribution. These disturbances may cause failures across all the electrical devices connected to the network. Harmonic currents have negative effects on nearly all the components in the electrical system, creating new dielectric, thermal, and/or mechanical stresses.
