GENERAL CHARACTERISTICS
The three-phase transformers used in this catalog are designed and implemented with the following
characteristics:
ELECTRICAL CHARACTERISTICS
The voltage drops vacuum are particularly dependent on output. In the product details listed in the catalog shows the data referred to:
WINDING CONNECTING
The table shows the conventional names corresponding to the connection of primary and secondary windings and groups normally used and preferred. Usually the three-phase transformers are AHU made with primary and secondary windings connected to the star with neutral accessible.
At the request of the terminal primary windings are taken to the terminal to allow connection to the star or triangle to work with reduced tensions relationship V3.
The three-phase transformers are AHU normally made in implementing open with a degree of protection IP00. However, they may also be supplied in container sheet steel painted with a degree of protection IP23
WARNINGS FOR WIRING
Verify that the processors into the temperatures do not exceed the limits prescribed by the rules.
Use the appropriate cables according to the current game and the capacity of the terminals. In addition to special care not to tighten the insulating sheaths under the terminal screws. In fact, a bad contact can lead to localized heating that can lead to damage to components.
The installation and replacement of transformers is to be performed by qualified persons.
