Unbalanced Load Monitoring

NOTE

All percentage values refer to a percentage of the generator rated power (Parameter 33; page 26).

Function: "Generator load imbalance not within the permissible range" - The percentage threshold value speci-

fies the permissible deviation of one phase current to the arithmetic mean value of all three phase currents.

Parameter 186

Load unbalanced

monitoring ON

Unbalanced load monitoring ON/OFF

ON ................ Monitoring for unbalanced load of the generator real power will be

performed. The subsequent parameters of this function are displayed.

OFF .............. Monitoring is disabled, and the subsequent screens of this function

are not displayed.

Parameter 187

Load unbalanced

max. 000%

Maximum permissible unbalanced load 0 to 100 %

If the threshold value has been exceeded for at least the delay time (Parameter 188;

e.g. because of an asymmetric load), the following alarm class is initiated.

Issuing of class F3 alarm

Parameter 188

Load unbalanced

delay 00.00s

Unbalanced load monitoring delay 0.02 to 9.98 s

For the control unit to recognize an unbalanced load monitoring fault condition, the

threshold value configured in Parameter 187 must be exceeded without interruption

for t

his period of time.
