Product Code : SCL-EELE-12837
Indian Lab Suppliers supplies the Power Factor Demonstrator (Product ID: 12837) as part of its electronics engineering lab equipment range. It is a bench unit that shows how resistive, inductive and capacitive loads change power factor, and how that power factor can be corrected.
Quick Answer
Built-in resistors (500, 400, 200 and 400 Ω), capacitors (12.5 µF and 20 µF, 440/450 V) and a 200 mH, 1 A inductor are combined into R, R-L, R-C and R-L-C loads. A microcontroller measuring unit shows voltage, current, power and power factor together on a 16 × 2 LCD, so students can relate real, reactive and apparent power and see the current lag or move ahead of the voltage. Isolated BNC outputs let voltage and current be viewed together on an oscilloscope, and correction is tried by adding a capacitor to an R-L load or an inductor to R-C and R-L-C loads. It runs from 230 V mains; switch off before rewiring, as capacitors can hold charge.
