Question

A long shunt compound generator supplies 100 A at a terminal voltage of 250 V. The resistance of the armature, shunt field and series field are respectively 0.02?,50? 0.05? The bhp of the driving engine is 38 Calculate the stray power losses.

Answer 1

To calculate the stray power losses in a long shunt compound generator, we need to follow these steps:1. Calculate the total current flowing through the generator: I_total = I_armature + I_series + I_shunt I_total = 100 A2. Calculate the voltage drop across the armature resistance: V_armature = I_total * R_armature V_armature = 100 A * 0.02 Ω V_armature = 2 V3. Calculate the voltage drop across the shunt field resistance: V_shunt = I_shunt * R_shunt V_shunt = 100 A * 50 Ω V_shunt = 5000 V4. Calculate the voltage drop across the series field resistance: V_series = I_series * R_series V_series = 100 A * 0.05 Ω V_series = 5 V5. Calculate the total voltage drop: V_drop = V_armature + V_shunt + V_series V_drop = 2 V + 5000 V + 5 V V_drop = 5007 V6. Calculate the stray power losses: Stray power losses = V_drop * I_total Stray power losses = 5007 V * 100 A Stray power losses = 500700 W or 500.7 kWTherefore, the stray power losses in the long shunt compound generator are 500.7 kW.
