ELECTRICAL SYSTEM AND METHOD FOR THE OPERATION THEREOF

摘要

The invention relates, among other things, to a method for controlling an electrical system (90), in particular an energy distribution system, comprising at least one transformer (92). According to the invention, the temperature in the interior of the transformer (92) is measured so as to form a inner temperature reading (Ti), a current reading (I) is measured, which indicates the current flowing through the transformer (92) on the primary side or the secondary side of the transformer (92) or is proportional to said current, in the case of an overload current situation the inner temperature reading (Ti) and the current reading (I) are used to determine how long the overload current situation can last before the temperature in the interior of the transformer has reached or exceeds a predetermined maximum temperature, and the further control of the electrical system (90) takes place in consideration of the determined time period (tmax).
