Pole discrepancy protection CCRPLD (52PD)
Main menu/Settings/Setting Group N/Current protection/PoleDiscordance(RPLD,
52PD)/PD
Displays instances of CCRPLD (52PD) with some settings per instance. The settings
are for operation, base current, trip time delay, contact function selection, current
function selection, asymmetrical magnitude of current and current release threshold.
