Abstract
This standard applies to incoming filters used to control the coupling of signals between the utility area and the consumer area (see Figure 1).
The standard defines
• the minimum impedance in the relevant frequency band(s) at both Utility port and Consumer port,
• the minimum attenuation of unwanted signals transmitted from the utility side to the consumer side and vice versa,
• the transmission characteristics:
- operating frequency domain for both utility side and consumer side,
- attenuation between the utility side and the consumer side and vice versa,
- impedance at the utility side and at the consumer side.
This standard applies to incoming filters designed for and used in single or multiphase installations.
