8BCONTROL FUNCTIONS
PROTECTION, CONTROL AND METERING FUNCTIONS
It changes the group of settings depending on whether the current
comes from the source side or the load side.
When the configured safety time passes after a reconfiguration, the
recloser does not operate with a single trip scheme, but with a reclosing
cycle..
Upon detecting absence of voltage on both sides of the breaker, it closes
after a programmed time passes.
Being closed, if the power flow drops below an adjustable value for an
also configurable time, it opens.
Being closed, if the power flow is reversed, it opens after this condition is
maintained for a configurable time.
Intermediate Recloser RTI:
Upon detecting a fault, it performs its reclosing cycle.
If it detects absence of voltage on either side, after a configurable time, it
changes to the alternative settings group and stays prepared for a
reversal in the flow of power.
It operates with a single trip scheme after the change in direction of
power flow, during a configurable safety time.
It operates with reclosing cycle in either direction after the safety time
passes.
It closes upon detecting voltage on both sides.
It changes the settings group automatically according to the power flow
after a load transfer
2.8.2. AUXILIARY VOLTAGE SELF-DIAGNOSTICS
In some applications the smART P500is part of a control cabinet which has batteries
and in these cases, some battery status tests must be performed periodically in order to
check how they are working.
