• Format: Transparent
• Maximum channel delay
•
Loop time <40 ms continuous (2 x 20 ms)
IED with echo synchronization of differential clock (without GPS clock)
• Both channels must have the same route with maximum asymmetry of 0,2-0,5 ms,
depending on set sensitivity of the differential protection.
• A fixed asymmetry can be compensated (setting of asymmetric delay in built in
HMI or the parameter setting tool PST).
IED with GPS clock
• Independent of asymmetry.
