1. A method for determining an electrical characteristic at a spinning machine or winder, wherein the electrical characteristic is one or both of electrical power and electrical energy consumption, the spinning machine or winder comprising a plurality of adjacently arranged workstations that each include at least one electrical working element, the method comprising:
measuring a total electrical characteristic for the spinning machine or winder with a central measuring unit;
subdividing the workstations into at least two production groups, wherein each production group comprises a group of the workstations configured to produce a product having common yarn parameters such that different production groups produce different respective products having different yarn parameters, the production groups being operated independently of one another;
defining a distribution key as a ratio distribution based on the electrical characteristic of the electrical working elements operating within each respective production group;
calculating the electrical characteristic specific to each of the production groups by allocating the total electrical characteristic between the production groups based on the ratio distribution of the distribution key; and
performing one or both of: displaying the production group electrical characteristic specific to each production group at the spinning machine or winder; or transmitting the electrical characteristic specific to each production group to a computer that is at a higher control level than the spinning machine or winder.
