Loading Inductor 2.5KVAR Bank
Product Code : SCL-EAE-11309
Quick answer: The Loading Inductor 2.5 kVAR Bank is an inductive reactive-load bank rated at 2.5 kVAR. It causes current to lag voltage in a compatible AC circuit, so students can distinguish watts, volt-amperes and VAR, measure lagging power factor and then correct it with a capacitor bank. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and technical institutes.

How lagging power factor is measured and corrected
Three different powers appear in an AC circuit with an inductive load. The wattmeter reads active power P in watts, the product of the voltmeter and ammeter readings gives apparent power S in volt-amperes, and the remainder is reactive power Q in VAR, where Q = sqrt(S^2 - P^2). The ratio P/S is the power factor, and with the 2.5 kVAR inductor bank connected it is lagging.
Once the lagging power factor has been measured, a compatible capacitor bank is switched in parallel with the inductor bank in steps. Each step supplies reactive power of the opposite sign: the ammeter reading drops while the wattmeter reading stays nearly the same, and the power factor rises. Adding too much capacitance swings the current ahead of the voltage, which shows students why correction has to be sized with care.
- Verify the rated voltage, current, frequency, phase arrangement and 2.5 kVAR capacity against the source.
- Set all load-selection switches to off and isolate the supply.
- Connect the bank with a voltmeter, ammeter and wattmeter in the supply circuit.
- Switch on, apply the inductive load in steps and record V, I and P at each step.

Frequently asked questions
How is power factor calculated from meter readings?
Divide the wattmeter reading by the product of the voltmeter and ammeter readings: power factor = P / (V x I). With this inductor bank connected, the power factor is lagging.
Can the inductor bank be used with a capacitor bank?
Yes. Connecting a compatible capacitor bank in parallel is the standard power factor correction experiment; the capacitor's reactive power offsets that of the inductor bank.
