The 

Blocking mode setting has three blocking methods. In the "Freeze timers"

mode, the operation timer is frozen to the prevailing value, but the 

OPERATE

 output

is not deactivated when blocking is activated. In the "Block all" mode, the whole

function is blocked and the timers are reset. In the "Block OPERATE output" mode,

the function operates normally but the 

OPERATE

 output is not activated.

4.3.1.5

Application

Since the negative sequence current quantities are not present during normal,

balanced load conditions, the negative sequence overcurrent protection elements

can be set for faster and more sensitive operation than the normal phase-

overcurrent protection for fault conditions occurring between two phases. The

negative sequence overcurrent protection also provides a back-up protection

functionality for the feeder earth-fault protection in solid and low resistance

earthed networks.
The negative sequence overcurrent protection provides the back-up earth-fault

protection on the high voltage side of a delta-wye connected power transformer

for earth faults taking place on the wye-connected low voltage side. If an earth fault

occurs on the wye-connected side of the power transformer, negative sequence

current quantities appear on the delta-connected side of the power transformer.
The most common application for the negative sequence overcurrent protection is

probably rotating machines, where negative sequence current quantities indicate

unbalanced loading conditions (unsymmetrical voltages). Unbalanced loading

normally causes extensive heating of the machine and can result in severe damages

even over a relatively short time period.
Multiple time curves and time multiplier settings are also available for coordinating

with other devices in the system.
