Loading Capacitor 3KVAR Bank
Product Code : SCL-EAE-11316
Quick answer: The Loading Capacitor 3 kVAR Bank is a capacitive load with a stated reactive-power capacity of 3 kVAR. In an AC circuit its current leads the voltage, so it can offset part of the lagging reactive power of a suitably rated inductive load, supporting power factor correction and R-L-C comparison practicals. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and technical institutes.

How the capacitor bank is used in AC practicals
A capacitor's opposition to AC is its capacitive reactance, X_C = 1 / (2 pi f C), which falls as frequency rises. The reactive power it supplies is Q = V^2 / X_C = 2 pi f C V^2, so it grows with the square of the voltage: a bank rated 3 kVAR delivers that figure only at its rated voltage and frequency. In an ideal capacitor the current leads the voltage by 90 degrees.
In the power factor experiment the bank is connected in parallel with a compatible inductive load. The reactive powers of the two partly cancel, the supply current drops for the same wattmeter reading, and the power factor rises. Comparing this with a purely resistive load and with the inductive load alone gives students a full picture of R, L and C behaviour.
- Confirm the approved voltage, frequency, phase and reactive-power ratings.
- Place the bank in a dry, stable, ventilated area and isolate the supply.
- Inspect earthing, terminals, cables and switching before connecting.
- Connect the bank as per the approved diagram, energise, and record voltage, current and power.
- After switching off, allow the capacitors to discharge before touching any terminal.

Frequently asked questions
Why does a capacitor bank's kVAR depend on voltage?
Its reactive power is Q = 2 pi f C V^2, so it changes with the square of the voltage. A 3 kVAR rating applies only at the bank's rated voltage and frequency.
Is it safe to touch a capacitor bank right after switching off?
No. Capacitors can hold charge after the supply is removed. Allow them to discharge, and check the discharge arrangement of the supplied bank, before handling the terminals.
