Introduce:
This series transformer with the relay DD11/60 type,when the scope of protectionwithin a groundfault.Residual current in the transformer secondary circuit.When the current reaches a certain value,the relay action.
Mainfeatures:
-
Series transformer with high permeability toroidal core.
- And annealing process,the secondary winding around the two sections in the core clamping core folder support transformer termial block and groud bolt and mounting hole in the folder on the folder on the user’s three-phase cable through the core window.
- Transformer primary winding.
