Application of AZ current transformers
- For voltage and current measurement systems: up to 25 A (current power up to 5.75 kW); up to 40 A (current power up to 9.20 kW); up to 50 A (current power up to 11.50 kW)
- For 3-phase installation, maximum building connection power approx. 5.75 x 3 = 17.25 kW (AZ0500 transformer); 9.20 x 3 = 27.60 kW (AZ0750 transformer); 11.50 x 3 = 34.50 kW (AZ1000 transformer)
- Required use of four transformers for 1- or 3-phase inverter and 3-phase electrical system
Selection and installation of current transformers in an inverter system
The number of transformers necessary for the application depends on the number of phases in the internal electrical system and the number of phases of the inverter. Current transformers must be installed according to their intended use and the diagram according to the OPTI-ENER installation and start-up instructions.
