BS EN 50065-4-3:2003 PDF

1   Scope 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.
