Voltage phase imbalance exceeds the set
threshold
Current phase imbalance exceeds the set
threshold
Voltage greater than the upper threshold
Voltage greater than the upper threshold
Voltage greater than the upper threshold
Voltage less than acceptable (No voltage) limit
Voltage less than acceptable (No voltage) limit
Voltage less than acceptable (No voltage) limit
Current exceeds upper threshold limit
Current exceeds upper threshold limit
Current exceeds upper threshold limit
All currents were measured below their
acceptable (No current) limits
One or more currents were measured below
their acceptable limits
One or two voltage phases were compatible with
zero (below No voltage limit)
All the voltage phases were compatible with zero
(below No voltage limit)
The power lines were not sufficiently stable to
allow the algorithm to obtain data (amplitude
and frequency variations of current and voltage
were excessive)
General fault consisting of one or more of:
No data obtained, no zero crossings detected,
perfect phase balance (voltage or current)
The phase ordering used by eMCM is incorrect
and must be rectified.
Voltage phase angles incompatible with 120º
were detected
The measured phase angle between
corresponding voltage and current channels was
not in the range: 0 <= <= /2
The ordering of the current phases was different
to that of the voltage phases or the angle
between two phases was not 120º to that of the
voltage phases or the angle between two phases
was not 120º
An unexpected or general error occurred
Division by zero was attempted during data
acquisition
