“…However, power measurements with these devices are specified for sinewaves or a limited combination of sinewaves. A calorimetric approach exists for power measurements at electric drives besides the digital sampling approach [2,8]. The calorimetric method measures directly heat losses.…”

Power analyzer specify their power measurement accuracy typically for sinusoidal signals only. In inverter applications, however, signals result from a switching operation and are therefore broadband. This article presents a method for providing a reference result for AC power measurements between inverter and motor. The reference power is determined by a combination of DC measurements and calorimetry and therefore it is independent of the AC signal's waveform.

“…The double-jacketed, closed-type calorimeter with water as a coolant is introduced, for example, in [9] and an improvement to the system is p r e s e n t e di n [ 10]. The double-jacketed calorimeter design is further improved, and it is used to obtain losses of mobile chargers and fluorescent lamps in [11][12][13]. The double-jacketed closed-type calorimeter is also used in [14,15].…”

Accurate measurement of power losses in high-efficiency devices is difficult. Measurement standards for industrial converters and complete electric drives, including both motors and converters, will come into effect soon, and measurement methods for these devices should be included. In the calorimetric method, the power losses are measured directly. However, the calorimeters presented previously are mainly tailored systems, and therefore, they typically have very complicated constructions. Hence, their applicability to the evaluation of general electric drives is limited. A functional calorimetric measurement concept is suggested in this study for power losses up to 2 kW. Such a power loss can be applied with presentday power electronic converters up to 110 kW. The construction of the concept is simple and lightweight. It does not require a complex structure or a large area in the measurement site. The concept is scalable and duplicable for different sizes. Different devices with different cablings can be measured without any problems. The combined standard heat loss measurement uncertainty for the calorimeter is ±0.4%.
