5.9.9
Over Load Protection
With this function it is possible to select if Current %, Active Current or Reactive Current is used for
over load protection. Over Load is based on internal counter that is increased when input value is
above 105 % level and decreased when below 105 % level. The increase and decrease occurs every
100 ms.
Tripping is made when over load counter value is over 10 000.
With parameters you can define the increase (Over load maximum step) at maximum defined input
level (Over Load Maximum Input). These points define the slope for the function. For example, if the
input value is in the middle of 105 % and Over Load Maximum Input values, the counter is increased
by a half of the Over Load Maximum step.
