PROTECTION, CONTROL AND METERING FUNCTIONS

Just as for the rest of the protection functions a set of setting tables exist for this
function:

Phase instantaneous/definite time/inverse time.

Neutral instantaneous/definite time/inverse time.

Sensitive instantaneous/definite time/inverse time.
Grouped into “Cold load pickup” there are the settings that define the operation of the

“Cold load” function enable: YES/NO

“Cold load” time: 0 to 10000 second

During this time, all the overcurrent protection settings (phase, neutral and
sensitive neutral) stop corresponding to the “active table” and start
corresponding to the “cold load” settings: enabling actions, pickups, curves,
times etc
Remarks:


The function “cold load” is de-activated while the unit is on “ongoing cycle”, this
means while the closing control is assumed by the Reclosing function

The function “cold load” does not operate on the “High Current Lockup”
settings.
