84 • Settings Calculation Examples
This chapter provides settings calculation examples for setting the BE1-11m for an induction motor and a
synchronous motor.
Induction Motor Settings Calculation Example
This example uses a 2,900 HP, 4-kV motor with six leads (stator neutrals brought out for differential
protection) and thermal model protection, as well as RTD (Resistance Temperature Detector) backup.
The power system to which the motor connects is solidly grounded. A single-line drawing is shown in
Figure 84-1.
