When there are many sources it is important to determine the sound power and directivity of each to determine their relative contributions to the noise problem. The radiated sound power and directivity of sources can be determined by reference to the equipment manufacturer's data (ISO 4871) or by measurement, using methods outlined in chapter 1.

target power factor is met. Reactive Power mode If this mode is enabled in an inverter, then the maximum ratio of the reactive power (Vars) to the rated apparent power (VA) should be . The electrical distributor can fix the reactive power at a constant value depending on the grid requirement. This means that the power factor may fall below
