ZES ZIMMER at the „Watt’s Cooking“ Seminar 2025

Power Seminar “Watt's Cooking?” – Precise Efficiency and Power Analysis with ZES ZIMMER

“Watt’s Cooking?” is more than just a seminar. It’s an intensive, hands-on experience that equips participants with the knowledge and skills to get the most out of their measurement equipment. Solid theory is combined with in-depth concept comparisons, practical tips on circuit design and signal probing, and proven methods for fault analysis.

The performance of modern electronic systems is growing rapidly – and with it, the demands for their precise analysis and optimization. ZES ZIMMER, the world's leading provider of high-precision power measurement technology, has risen to this challenge and, with the LMG600 series and its expertise, offers the ideal devices for developers, manufacturers and operators.

New Knowledge, Practical Application: “Watt's Cooking?” Seminar

To share this knowledge, the “Watt’s Cooking” seminar focuses on the correct use of measuring technology. This seminar is a combination of solid theory and hands-on live demonstrations.

Grasping the Theory: Fundamentals for Precise Measurements

In the theoretical part of the seminar, Florian Schmolt, application engineer at ZES ZIMMER, explained the fundamental prerequisites for measurement on a three-phase induction motor. He demonstrated how to correctly connect the LMG671, how to best group measurement channels, and how to perform the star-delta conversion to accurately determine phase currents and power. At ZES ZIMMER, we emphasise particulary on measurement accuracy, which is essential for determining efficiency.

Furthermore, Florian Schmolt highlighted the possibilities of capturing mechanical variables such as speed and torque with the LMG671. By controlling the electromagnetic brake from the PSI card (process signal interface) of the LMG671, we were able to demonstrate measurements of mechanical power and overall efficiency.

Live Demo: Practice Meets Innovation

The theory was put into practice in the live demo. Florian Schmolt showed how a three-phase induction motor with inverter control, brake, speed and torque measurement can be analyzed in practice. The audience was able to experience outstanding measurement technology which helps our customers optimizing their products and making them ready-to-market.
