Methodology, equipment, precision, immunity to electromagnetic emissions and reliable measurement result are important questions for electrical energy measurements Widely used smart energy meters show good results under laboratory tests and in ordinary applications but are not very suitable for industrial digital electrical energy supply environment. A different method and inexpensive equipment are used to overcome mentioned. Measured power balance between 15 robotized manufacturing cell measurement points (only power losses in cables aren’t measured) are in range of 1,8% (measurement data rate 20ms), in spite of high level of electromagnetic emissions inside and outside of electric cabinets created by power converters.
