Loading Inductor 1.2KVAR Bank
Product Code : SCL-EAE-11308
Quick answer: The Loading Inductor 1.2 kVAR Bank is an inductive AC reactive load rated at 1.2 kVAR. Connected to a compatible AC source, it draws current that lags the voltage, so students can study phase relationships and reactive power and, with a matching capacitive load, see inductive and capacitive reactive power cancel. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and technical institutes.

How the inductor bank is used in AC circuit practicals
The opposition an inductor offers to AC is its inductive reactance, X_L = 2 pi f L, which rises with frequency. At a given voltage V the reactive power it takes is Q = V^2 / X_L, and the current lags the voltage. Measuring V, I and P on this load shows students that the coil current is out of step with the voltage, and why a wattmeter reads far less than V x I.
Because inductive and capacitive reactive powers have opposite signs, connecting this bank alongside a capacitive load of equal kVAR rating at the same voltage and frequency lets the class see the reactive powers balance, leaving the source to supply mainly active power. It is a direct way to teach the basis of power factor correction.
- Confirm the source voltage, frequency, phase, current and protection requirements.
- Place the unit on a dry, stable, adequately ventilated bench or floor area.
- With the source off, connect the bank through a voltmeter, ammeter and wattmeter.
- Energise the circuit, record the readings, and compare them with a resistive load drawing a similar current.

Frequently asked questions
What is the reactive power of an inductor?
It is the power exchanged each cycle between the source and the inductor's magnetic field, Q = V^2 / X_L, measured in VAR or kVAR. It is not converted to heat, which is why a wattmeter reads little on an inductive load.
Which loading inductor rating is right for a lab?
Match the kVAR rating, voltage, frequency and phase to the source and the planned experiments. Loading inductors are listed at 1.2, 2.4 and 2.5 kVAR; state the source ratings in the enquiry.
