6.4.1 Power Quality
PATH: ACTUAL VALUES  A3 POWER ANALYSIS  POWER QUALITY VALUES
•Ia/Ib/Ic CREST FACTOR: The crest factor describes how much the load current can 
vary from a pure sine wave while maintaining the system’s full rating. A completely 
linear load (pure sine wave) has a crest factor of   (1 /0.707), which is the ratio of the 
peak value of sine wave to its RMS value. Typically, the crest factor can range from   
to 2.5.
•Ia/Ib/Ic THDF: The Transformer Harmonic Derating Factor (THDF), also known as 
CBEMA factor, is def ined as the crest factor of a pure sine wave ( ) divided by the 
measured crest factor. This method is useful in cases where lower order harmonics are 
dominant . In a case where higher order harmonics are present , it may be necessary 
to use a more precise method (K-factor) of calculating the derating factor. This method 
also does not take into consideration the losses associated with rated eddy current in 
the transformer. The EnerVista PQMII Setup Software provides the K-factor method of 
calculating the derating factor, which is def ined on a per unit basis as follows:
(EQ 6.3)

6.4.5 Voltage Disturbance
Main Menu
PATH: ACTUAL VALUES  A3 POWER ANALYSIS  VOLTAGE DIST. RECORDER
The Voltage Disturbance Recorder runs continuously and records the source, level and 
duration of each voltage disturbance. Up to 500 disturbances are recorded in a circular 
buffer. When over 500 disturbances are recorded, data for older disturbances are lost as 
new disturbances are recorded. Additionally, since the events are stored within volatile 
memory, the voltage disturbance recorder will lose all events upon a power loss. The time 
and date of when the disturbance 
ended is recorded with the disturbance event . The 
following available is available for each disturbance:
•Type: Each disturbance is classif ied as a 
SWELL or SAG. The disturbance will be 
distinguished as a swell if the voltage increases above the swell level, for up to 1 
minute. A sag disturbance is distinguished in the same manner except that it involves 
a voltage decrease below the sag level.
•Source: The source of the disturbance is the phase voltage that recorded the 
disturbance; either Van, Vbn, Vcn, Vab, or Vca. If the disturbance is found on two or 
more phases, multiple disturbances will be recorded.
NoteThe voltage disturbance recorder monitors only measured values. Therefore, when the 
Vbc (delta connection only) and Vbn (2 VT 4-Wire Wye only) phases are calculated 
quantities, they are not considered a source.UNDERCURRENT ↓Undercurrent Alarm/Control Dropout

PATH: ACTUAL VALUES  A3 POWER ANALYSIS  VOLTAGE DIST...  1(500): 
The DURATION is the length of time of the disturbance. If the disturbance is either a sag or a 
swell the duration will be recorded in cycles with a maximum possible value of 1 minute 
(3600 cycles at 60Hz).
The 
VOLTAGE LEVEL represents the average level in volts for the disturbance.
NoteThe voltage disturbance recorder is independent from the event recorder. The alarm 
events will record normally as per the conditions set within the 
S4 ALARMS  CONTROL 
settings menu, regardless whether the voltage disturbance recorder is enabled or of 
the sag/swell level.
If an undervoltage/overvoltage alarm occurs, it is immediately recorded as an event (if 
enabled). On the other hand, the voltage disturbance is recorded, if enabled, once the 
voltage level returns to nominal and the condition is complete. As a result , the time 
recorded in the event recorder is the start time of the alarm condition, while the time 
recorded in the disturbance recorder is the end time of the condition.
