Loading Capacitor 1.2KVAR Bank
Product Code : SCL-EAE-11307
Quick answer: The Loading Capacitor 1.2 kVAR Bank is a capacitive reactive-load bank rated at 1.2 kVAR. Its current leads the applied voltage, so it offsets the lagging current of motors and inductive loads, letting students carry out power factor correction and compare resistive, inductive and capacitive loading. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and technical institutes.

How power factor correction is demonstrated
A capacitor draws current that leads the voltage, the opposite of an inductor. Its reactive power therefore has the opposite sign, so when a capacitor bank is connected in parallel with an inductive load the two reactive powers partly cancel. The source then supplies less reactive power, the line current falls for the same useful power, and the power factor moves towards unity.
The capacitor reactive power needed to raise the power factor of a load of active power P from cos phi1 to cos phi2 is Qc = P (tan phi1 - tan phi2). Students can calculate this, switch in the capacitor bank, and check the result against their meter readings.
- Verify the rated voltage, frequency, phase and maximum reactive-power capacity.
- Place all capacitor load switches in the off position.
- Isolate the AC supply and connect the bank in parallel with the inductive load, with meters in the supply line.
- Switch on, record V, I and P for the inductive load alone, then switch in the capacitor steps and record again.
After switching off, allow time for the capacitors to discharge before touching the terminals.

Frequently asked questions
What is a loading capacitor bank used for?
It provides a capacitive load whose current leads the voltage. In the laboratory it is used to correct the lagging power factor of inductive loads and to compare resistive, inductive and capacitive load behaviour.
How does a capacitor bank improve power factor?
Its reactive power, opposite in sign to that of an inductor, cancels part of the reactive power drawn by an inductive load. The source then supplies less reactive power and the power factor rises towards unity.
