• Energy Valuation - PowerPad IV Class A Model 8345 offers all the measurements required to successfully implement energy efficiency projects and monitor electricity distribution.

• Line Carrier Signal Measurement - In the harmonic analysis function, there is also a mode for monitoring carrier currents. After defining their frequency in the instrument, the command signals will then be measured.
• Interharmonics (Harmonic Mode) - Model 8345 can be used to measure and display the interharmonics, as requested in IEC 61000-4-7, for very precise analysis of all the disturbances on an electrical network.

• Trend - The trend graph shows the variations of the parameters measured over time as fast as 200ms.
• 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 - 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.
• True InRush - For tests when starting up loads, model 8345 can record 1/2 period values covering more than 30 minutes and the waveforms of the signal can be captured.

• Software - DataView control panel processes the measurements made with the PowerPad IV Class A Model 8345 (see below for details)
• Web Server - PowerPad IV Class A Model 8345 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 - AEMC IT networks are protected against external attack. Thanks to the provision of access to our 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 the 8345 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.
• Comms - In addition to using media such as SD cards and USB drivers, it is possible to download the measurements and communicate with the instrument remotely via USB, remote links, Wi-Fi (direct or via server) or the RJ45 (Ethernet connector).

• 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 and how to interpret the results. The measurement parameters are described for each applicable parameter in terms which provide reliable, repeatable results, however the method is implemented.
• EN 50160 Homogenous 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 61000-4-15 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 2 parameters calculated from the power supply voltage (1) Pst which is a short-term assessment based on a 10-minute observation period and (2) Plt which is a long-term assessment, usually over a period of 2 hours.

DataView - Data Analysis and Reporting Software

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 PowerPad IV Model 8345 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 operator comments and analysis.

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 set up is flexible and allows the user full customization. The progress of the measurement set up 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.

• Display and analyze real-time data on a PC
• Record trend data directly to the PC
• Create and store a complete library of configurations to be uploaded
• Customize views, templates and reports to meet specific needs
• Display waveforms, trend graphs, harmonic spectrums, text summaries, transients, event logs and stored alarms
• Print reports using standard or user designed custom templates

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. 

For energy diagnostics on 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 of a transformer, implementation of 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.

The increase of electrical power supplies in industrial processes has led to increases in harmonic disturbances on electrical networks which have a direct impact on the quality of the energy distributed. 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.
