Title:
A monitor method of a tap changer
Document Type and Number:
Japanese Patent JP6117338
Kind Code:
B2
Abstract:
The invention relates to a method for monitoring an on-load tap changer according to the known “windowing technique,” wherein for synchronization, the current (I) on the diverter switch is continuously detected, the effective value (Ieff) is calculated, which in turn is differentiated. The corresponding point in time, at which the maximum or minimum of the differentiated value occurs, is evaluated to be the moment for the diverter switch leap (tLU), and produces the synchronization impulse.
