A method monitors at least one item of inductive equipment. The method includes: performing an operation of recording real-time data relating to a current condition of the at least one item of inductive equipment; performing an operation of transferring the recorded real-time data to a monitoring unit assigned to the at least one item of equipment; performing an operation of ascertaining a condition factor of the at least one item of inductive equipment based on the real-time data; performing an operation of ascertaining a failure rate for the at least one item of inductive equipment on the basis of the condition factor; and performing an operation of determining a maximum permitted hotspot temperature on the basis of the failure rate.

Method and system for monitoring at least one inductive operating means

Transformers are in a parallel circuit in which a tap changer with a control sensor is associated with each of the transformers and all control sensors are connected together by a communications connection. Each control sensor generates a measurement that is transferred by the communications connection. A measurement is generated with each of the control sensors, and at least one of the measurements of the control sensors of the transformers by the communications connection is transferred to N&#x2212;1 control sensors. Then a controlling deviation caused by a circuit reactive current is calculated for each control sensor on the basis of the measurements of the control sensors. Finally the tap changer associated with each transformer is actuated by the respective control sensor as a function of the calculated controlling deviation such that minimization of the circuit reactive current is carried out for the respective transformer.
