Power Factor Load Bank
Product Code : LSK-EPS-10534
Power Factor Load Bank (SKU LSK-EPS-10534) is a free-standing, mobile load with separate resistive, inductive and capacitive banks, giving unity, lagging (inductive) or capacitive power factor for power systems experiments. It suits electrical machines and power systems laboratories in engineering colleges and polytechnics. Science Lab Supplies dispatches it from Ambala, India to institutions, tender contractors and distributors that need a predictable test load.
Specifications
Three independent lines, each with resistive, inductive and capacitive banks, can be connected as a star or delta load and set to different values for unbalanced tests. A voltage-selector switch adapts it to different line voltages, and small wheels and a worktop make it a mobile bench.

Applications and Experiments for the Power Factor Load Bank
The load bank gives students a known, repeatable load for generators, transformers and transmission line models. By switching capacitive banks against inductive ones they can also see how a static VAr compensator corrects power factor in industrial plants and large factories.
- B.E./B.Tech electrical machines: loading alternators and transformers at set power factors.
- Balanced and unbalanced three-phase load tests in star and delta.
- Power factor correction and the principle of static VAr compensation.
- Diploma power systems practicals: voltage regulation under changing load.
The unit carries mains-level voltages, so connect it with the supply switched off and supervise all tests.
Standard Scope of Supply
The Power Factor Load Bank is supplied as a single mobile unit containing all three load banks on their three lines, with the voltage selector and worktop as described above. Supplies, meters and the machines under test are separate items, and any optional accessories are listed on the quotation.
Packing, MOQ and Lead Time
We can quote one load bank or several for parallel lab benches. The quotation sets out packing, delivery time and price for the number of units requested, and the resistive load bank or other engineering lab equipment in India from the power system range can be included too.
Registered as an exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Malaysia, Peru, Egypt, Iraq, Nigeria and Kenya. Requests reach us through the enquiry cart or the contact page, and tender buyers can refer to the lab tender page.
Frequently Asked Questions
Can it give a capacitive power factor?
Yes. Combining the capacitive bank with the resistive bank makes the current lead the voltage, the inductive bank makes it lag, and the resistive bank alone gives unity.
Does it work on single-phase circuits?
Yes. It has three independent inputs, so one line can serve a single-phase circuit, or all three can form a star or delta load on a three-phase system.
Who supplies the Power Factor Load Bank?
Science Lab Supplies supplies this unit from Ambala, India to colleges and contractors, together with the other power system trainers if needed.
How is it moved between benches?
It stands on small wheels, so it can be rolled into place for a practical and cleared away afterwards, which saves setting-up time.
