6BPOWER QUALITY
PROTECTION, CONTROL AND METERING FUNCTIONS
Voltages of the three phases:
Stores the value of the phase voltages at the
moment of the detection of the phase loss.
2.6.8. POWER OUTAGES
A power outage is the variation of the voltage at the mains of the relay below a certain
user defined level. The relay records the following information regarding such events:
Power outage counter:
Indicates the number of this kind of events that have
been detected including the present one. This counter has a maximum limit of
100 after which it changes to zero.
Date and time:
Date and time when the event was detected.
Event duration:
Time span of the event.
Involved phases:
Information about the phases where the event was detected.
Voltages:
Stores the value of the voltages at the moment of the detection of the
power outage.
2.6.9. FREQUENCY VARIATION
A frequency variation is a deviation above or below a user defined threshold from the
nominal value of the frequency. The relay records the following information regarding
such events:
Counter of Hz events:
Indicates the number of this kind of events that have been
detected including the present one. This counter has a maximum limit of 100 after
which it changes to zero.
Date and time:
Date and time when the event was detected.
Event duration:
Time span of the event.
Frequency:
Maximum or minimum value of the frequency during the event.
