
Supply Voltage Unbalance OK/FAIL: Voltage unbalance is evaluated at intervals of 10 min.
within observation window of 1 week. Evaluation is only at intervals in which voltage is inside
nominal boundary of [+15.0%,-15.0%]. Unbalance limit N1 is set to 2.00% and must be kept
95.0% of observation time. Intervals with voltage interruption are discarded. Intervals with
DIPS or Over voltage are discarded.
COMPLIANCE SUMMARY SECTION:

The Compliance Type is configured when Setting your Instrument in PQ Compliance
Configuration.

Running Status means whether or not the BLACKBOX’s Power Quality engine is evaluating the
power quality according to the Configured PQ Compliance.

The Embedded Report field further indicates a type of report that is auto-generated
internally in the device's file system. Most compliance types do not generate any specific
report, & therefore, the report type will be
None . However, CREG type of compliance (used
in Colombia) also auto-generates a specific format of Report Files as defined by the local
regulator.

The Evaluation Status field provides an overall status of PASS or FAIL of the entire
compliance. Anytime the evaluation period is not complete (typically required is a 1 week
observation), the status will be
N/A (Not Available), otherwise PASS will be indicated as OK.

The Start Time field shows the last time the compliance engine was restarted. The entire
state & observation window history is stored on the internal non-volatile memory, so even
after powering down; the Engine will continue its evaluation & maintain all indications.
(Start time remains unchanged after device powered up.)

The Window Time On/Off fields specify how much aggregated time is already in the
observation window. ON refers to the aggregated window time the device was powered on &
OFF refers to the amount of window time the device power was off. The format presented
is [Days: Hours: Minutes: Seconds]. Ideally the OFF time is all zeroes & the ON time is 7 days
(which is the typical full observation period in most of the compliance types). Once the
observation window reaches 7 days, it will start to slide in steps of 2 hours. Sliding means
the information from the oldest 2 hours is being dropped, where a new up-to-date 2-hour
interval is being used for calculations.

The Measurement Flag field indicates whether there is a power quality event such as a
DIP/SWELL or INTERRUPTION at the moment.
