Typically, teleprotection signals carried over packet networks use a technology known as pseudowire emulation, which creates a tunnel for them through the packet network. The key criteria for measuring teleprotection performance are: Command transmission time, the overall operating time for a teleprotection system.

Testing a distributed distance protection with teleprotection used to be quite time-consuming, since test plans to be executed simultaneously at the ends have to be precisely coordinated. Testing a three-terminal line protection is even more complicated and costly than protecting a simple overhead line with only two ends.

Teleprotection scheme The most desirable scheme is obviously one which combines the best features of both arrangements, that is, instantaneous tripping over the whole feeder length plus back-up protection to adjacent feeder.
