Loading Rheostat 3.5KW Bank Three Phase
Product Code : SCL-EAE-11314
Quick answer: The Loading Rheostat 3.5 kW Bank Three Phase is a three-phase resistive load bank with a capacity of 3.5 kW. It lets a three-phase alternator, generator or machine trainer be tested on load rather than only at no load, for three-phase power, voltage-regulation and load-characteristic experiments. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and technical institutes.

How the three-phase load bank is used
With equal resistance in each phase the bank forms a balanced three-phase load at unity power factor. The total power it absorbs is then P = sqrt(3) x V_L x I_L, where V_L is the line voltage and I_L the line current, and every line carries the same current.
In an alternator load test the machine is run at rated speed and voltage, the three-phase load is applied in steps, and line voltage, line current and power are recorded. With the two-wattmeter method on a balanced resistive load the two readings come out equal, a neat check that students can compare with an inductive load, where the readings differ.
- Check that the supply voltage, frequency and current suit the bank's total load rating.
- With the source isolated, verify the phase sequence and connect the three phases through the meters.
- Run the alternator or machine to rated conditions at no load and note the readings.
- Apply the load in steps, keeping speed constant, and record line voltage, line current and power at each step.

Frequently asked questions
How is power calculated for a balanced three-phase resistive load?
P = sqrt(3) x line voltage x line current, since the power factor of a resistive load is unity. The two-wattmeter method gives two equal readings whose sum is the total power.
Is the 3.5 kW rating per phase or total?
The page does not state this. Confirm whether 3.5 kW is the total or the per-phase rating in the quotation, together with the voltage and current ratings.
