NOTE!
The values shown in Table 5.1 on page 5-2 are standard values, however, they may change due to the special characteristics
of the product:
Transformer configurations;
Input switchgear;
Compartment for dynamic braking;
Exciter compartment (for synchronous machines);
Output filters;
Input filters (AFE);
Additional inverter compartment (AFE);
Special grounding and safety systems;
Special cooling system;
Transformer
An isolating transformer is required to provide the number of secondary windings necessary to the rectifier bridge and the appropriate voltage
level. The minimum specifications of the input transformer are:
Nominal power according to the inverter power rating considering the input current harmonics.
Minimum impedance of 6 %.
Shield between primary and secondary windings.
Primary voltage according to the available line voltage.
Secondary voltages according to the motor nominal voltage and 7.2 kV voltage insulation class.
