Description / Abstract:

Scope and object

This part of IEC 834 applies to narrowband and wideband teleprotection systems used to convey analogue information about the primary quantities such as phase or phase and amplitude. The teleprotection equipment can either be separate or integrated in one unit with the protection equipment or the telecommunication equipment.

Narrowband systems include systems operating within a 4 kHz band (for each direction of transmission).

Wide-band systems include systems occupying more than 4 kHz bandwidth (for each direction of transmission).

Broad-band command systems are not dealt with in this standard.

The object of this part of IEC 834 is to establish performance requirements and recommended testing methods for analogue comparison teleprotection equipments used in connection with power network protection systems and to define the associated terminology. The information conveyed and compared such as phase or phase and amplitude quantities can be in analogue or digital form.

In addition to the power supply and the interfaces belonging to the teleprotection equipment, the performance of the teleprotection equipment in conjunction with the protection equipment shall be tested.

All the tests should be considered as type tests (see IEC 50(151)).
