Software meets latest power test standards

ZES ZIMMER sits on international standards committees and it is quick to incorporate changes and update into the test systems. The measurement results and the limit values (either fixed or product-specific) defined in the standards are also visualised graphically. The analysis can be carried out either online, while directly connected to the measurement hardware, or offline, using stored data records.

Each data record is furnished with the basic characteristic data of the test sample (RMS values of voltage and current, active power, reactive power and apparent power, power factor, harmonic distortion, etc.) to increase the significance of the information and to avoid incorrect allocations.

The system is based on the ZES ZIMMER’s power analysis technology. A fast Ethernet interface (Gbit) guarantees smooth communication and data transfer between software and test hardware.The LMG Test Suite allows for quick identification of the cause of an inadequate test result. All measurements can be displayed and evaluated in the time domain alongside the familiar presentation in the frequency domain.

All harmonic frequencies can be isolated throughout the test and investigated to assist with localising the problem. In addition, all data can be passed on to third-party applications in full resolution using the clipboard or file export for additional analysis.

The LMG Test Suite supports all AC power sources available on the market which fulfil the requirements of the CE standards to be tested. This provides maximum flexibility for the customers. In particular, they can continue to use the sources that are already available and thus avoid additional investments.

Calibration of the AC power source specifically for the CE tests is not necessary, as the test system monitors compliance with the stipulated source parameters. For example, the system analyses the voltage harmonics and presents them graphically. This ensures freedom from distortion and voltage stability of the source. Any problems from this side of the test structure are thus excluded reliably. All results are documented in clear, comprehensive test reports in PDF format.

Alongside the stipulated measurement values, all of the information regarding measurement equipment, test structure and settings is also integrated into the test reports – such as type designations, serial numbers and information on the calibration and traceability of the measurement instruments used.

The reports can be supplemented with additional customer-specific information and design elements, in order to avoid unnecessary reworking of the reports outside the system.
