From measurement results of experiment 4 load) with inductive load L5 = 0.9 H and resistive load R3 = 435 we know that a cosφ2 value of about 0.5 occurs for this load case. Ω Set the inductive load Ls and resistive load R3. In order to determine the required capacitance for improving the power factor to about 0.9 change in steps the capacitance load values until power factor meter reads about 0.9. At this moment measure voltage U1, current I1, active Pi and reactive Q1 powers at the beginning of the line and voltage U2, current I2 and cosφ2 at the line end. Compensation capacitance: ………… μF U1 = V I1 = A P1 = W …………… …………… …………… Q1 = Var U2 = V I2 = A …………… …………… …………… cosφ2 = …………… Comparing these measurement results with those obtained under same ohmic-inductive load in the experiment 4, here, too, we see a significant improvement in the voltage at consumer, coupled with a reduction current. Moreover the desired power factor value can be achieved precisely.
