Application of ACX current transformers
- For voltage and current measurement systems: ACX1100 up to 100 A (current power up to 23.00 kW); ACX1150 up to 150 A (current power up to 34.50 kW)
- For 3-phase installation, maximum building connection power approx. 23.00 x 3 = 69.00 kW (ACX1100 transformer); 34.50 x 3 = 103.50 kW (ACX1150 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.
