摘要： A tap selector for a power transformer switchable under load is monitored by detecting the effective values of current and voltage of the drive motor of the tap changer. The power is calculated and from that the instantaneous torque and the latter is compared with setpoint values either of the torque and position of the tap selector or in terms of characteristic segments of the torque versus time graph with normalized segments of a setpoint graph so that, with serious deviation an immediate shutdown of tap selector operations is ensured or information can be generated as to trends or the need for maintenance.

摘要： A method of monitoring a tap changer in which measured values representing the status of the tap change operation are associated with positions of the tap changer and the position range or time range for the tap change is subdivided into partial intervals for which characteristic values of the measurement are calculated by a calculating rule, e.g. averaging. These characteristic values are compared with stored parameter data and operation categories are established which are then used exclusively for the further information processing.
