11. IEEE C37.94 ANALYZER OPTION
11.1 IEEE C37.94 Tele-protection
Power Lines have redundancy. Relays switching the redundant lines
are controlled by multiplexers and tele-protection circuits. Fiber
optic lines are preferred over copper lines to connect this
equipment due to their immunity to electrical noise.
In a typical tele-protection telecom network using IEEE C37.94
optical links, error free operation is of extreme importance to
assure positive Power Relay closure/opening and reporting of this
status.
A tester is needed to verify optical power and bit error free
operation of the optical link between the data multiplexer and
teleportation equipment. In addition, data propagation delay
should be measured.
