The two time parameters have the following meaning:
•
CLP switch time
: If the circuit has been open for less time than that set in this parameter, the Cold
Load Pickup is not activated. When this time is exceeded, the overcurrent functions are multiplied
by the indicated constant.
•
CLP duration
: Time from the passage of current in which time the Multiplier is applied to the
overcurrent functions tap. After this time, the relay returns to the adjusted taps
.
There is a conditioner in the multiplier. The maximum protection functions are located in their tap. This
maximum can never be exceeded, regardless of the adjusted tap in the protection function and the Cold
Load function multiplier.
The function operated according to the following automaton. The automaton consists of six statuses,
three of them with normal adjustment, and the other three with the extended adjustments. During transit,
the settings are maintained according to where they come from.
The current level is used to determine the change, more than the circuit breaker situation. If the current
less than 10% of the rated level, it is understood that the line is open, with an extremely low usage level
(operating at night, or on weekends). In one case or the other CLP must start.
The relay normally operates with the settings in their active table. When the circuit breaker opens, a
timer starts. The remote control could activate circuit breaker closure, and also, if a permanent fault
occurs the circuit breaker may open again. To prevent the increase counter from resetting there is a
condition which reduces the activation time from where it was. If the counter exceeds its limit, a switch
is made to Cold Load. On the contrary, if the counter reaches zero, a switch is made to the standby
condition. This mechanism is identical in Cold Load reset.
