Ideal For
Not Recommended For
For power transformers, ground the secondary winding at one point. Follow IEC 60076 for terminal markings: HV terminals (U, V, W) and LV terminals (u, v, w). Ensure proper polarity for parallel operation. Never operate with secondary open-circuited if CT integrated; for PT integrated, never short-circuit secondary while energized. Refer to nameplate for vector group and tap changer connections.
