Dynamic Load (Three-Phase)
Dynamic load for a three-phase power supply.
Description
The Dynamic Load (Three-Phase) unit implements dynamic loading for a three-phase power supply.
The table shows how the block calculates the active and reactive power consumption as a function of the supply voltage, .
| Range of values | Corresponding active and reactive power consumption |
