-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

3 Classification

The selection of the filter shall be made according to the local regulations

NOTE If there are no local regulations, Type 1 shall be used

3.1 Type 1

Satisfies both the utility and the consumer impedance requirements

3.2 Type 2

Satisfies only the utility impedance requirements

3.3 Type 3

Satisfies only the consumer impedance requirements

4 Incoming filter electrical characteristics

The filter shall meet the requirements given in EN 50065-4-1 and EN 50065-2 series

4.1 Overvoltage

Requirements in accordance with 7.1.5 of EN 50065-4-2:

- for the utility side: category IV;

- for the consumer side: category III

4.2 EMC

According to EN 50065-2-1 for the consumer side in residential, commercial and light industrial environments

According to EN 50065-2-2 for the consumer side in industrial environments

According to EN 50065-2-3 for the utility side

EN 50065-4-3:2003 - 6

-4.3 Operating frequency range

In the band 3 kHz to 148,5 kHz:

- 3 kHz to 95 kHz for the utility side,

- 95 kHz to 148,5 kHz for the consumer side

4.4 Impedance

a) Impedance at consumer side

At the consumer side of the incoming filter

• when measured in the operating frequency range from 95 kHz to 148,5 kHz,

• in accordance with 6.1 of EN 50065-4-1,

• the utility side loaded with RL,

the decoupling filter shall have an impedance modulus value on the consumer side in accordance with Figure 2

b) Impedance at the utility side

At the utility side of the incoming filter,

• when measured in the frequency range from 3 kHz to 95 kHz,

• in accordance with 6.1 of EN 50065-4-1,

• the consumer side loaded with RL,

the decoupling filter shall have an impedance modulus value on the utility side in accordance with Figure 2

c) Exception is made however for decoupling filter used to create a return path for the signal when needed (e.g common mode propagation), where the impedance may be lower when measured at the side of the decoupling filter where the return path or phase coupling is required
