These type-specific data are only valid in connection with the information contained in the general section (TD 61) since this section contains important information on such subjects as potential connection, leakage inductance, current division, and so on. Dimensional drawings and connection diagrams are subject to change without prior notice. Drawings submitted during bidding and ordering are always binding. Since the on-load tap-changer is delivered to the specifications of the transformer manufacturer, the transformer manufacturer is responsible for selecting the correct properties of the on-load tap-changer so that the requirements of the transformer are met. 124/03/01/0 TD 124/03 3  1 General 1 General 1.1 Summary of technical data The on-load tap-changers in all their specifications are subject to all relevant international and national guidelines and standards, particularly IEC Publication 60214 3ED 89 and the VDE standard DIN EN 60214 (VDE 0532 Teil 30): 1998-06.
