Product Code : SCL-EELE-12257
Indian Lab Suppliers supplies the Measurement of power & power factor of L-R Circuits with power supply and 4 meters (Product ID: 12257) as part of its electronics engineering lab equipment range. It is a board for measuring the power and power factor of a series R-L circuit on a single-phase AC supply using voltmeters and an ammeter.
Quick Answer
A 100 Ω, 20 W wire-wound resistor and a 200 mH, 500 mA inductor are connected in series across a transformer tapping of 10, 20, 30 or 40 V AC (±10%, 500 mA). Three 0–50 V AC voltmeters read the supply, resistor and inductor voltages, and a 0–500 mA AC ammeter reads the current, so power and power factor follow from the three-voltmeter method. The method also refers to a wattmeter, which is not among the listed meters, so please confirm at quotation whether one is supplied.
