    PGR-6150 Motor Protection System Rev. 1 _________________________________________________________________________________ 6.2.2. Overload The overload function meets international standard IEC 947-4-1 and IEC 255-8. A mathematically based thermal model is used to simulate the motor's thermal condition. The model combines two thermal images: A heating image and a cooling image. The heating image represents the thermal condition of the windings of the stator and rotor, and the cooling image represents the thermal condition of the motor housing.

  • Page 15: Phase Unbalance

    PGR-6150 Motor Protection System Rev. 1 _________________________________________________________________________________ The PGR-6150 allows for overload function settings between 1 and 2 times I . Note however that standard IEC-947-4-1 recommends the tap setting to be between 1.05 and 1.20 times I 6.2.3. Phase Unbalance The unbalance function is applied on a three phase system made up of three phase currents (IA, IB, IC).
