Scope

This part of IEC 60834 applies to teleprotection command systems used to convey command information, generally in conjunction with protection equipment. It aims at establishing performance requirements and recommended testing methods for command type teleprotection equipment. The information conveyed by the teleprotection equipment can be in analogue or digital form. In digital form, a distinction is made between serial and packet-based data.

The command type teleprotection equipment referred to in this standard can be:

a)      analogue teleprotection equipment such as analogue power line carrier equipment or voice frequency equipment, which is used in connection with various telecommunication systems, such as power line carrier (PLC), radio links, optical fibre, rented circuits, leased or privately owned cables.

b)      digital teleprotection equipment which is used with a digital telecommunication system (TDM based) or media such as optical fibres, radio links, leased or privately owned digital links.

c)      packet-based teleprotection equipment which is used with packet-switched telecommuni-cation networks such as Ethernet, IP, MPLS-TP, IP MPLS.

The command type teleprotection equipment may be separate, or provided as an integral part of the protection equipment, or as an integral part of the telecommunication equipment.

In addition to performance tests, EMC tests also shall be carried out on the teleprotection equipment. All the tests should be regarded as type tests.

NOTE According to the International Electrotechnical Vocabulary (IEV), a type test is defined as a test of one or more devices made to a certain design to show that the design meets certain specifications.
