Loading Rheostat 3KW Bank
Product Code : SCL-EAE-11311
Quick answer: The Loading Rheostat 3 kW Bank is a resistive load with a stated capacity of 3 kW. It converts electrical energy into heat while a generator, alternator or other source is tested under load, so students can follow terminal voltage from no load to full load and work out regulation and efficiency. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and technical institutes.

How the voltage regulation test is done
Every practical source has some internal impedance, so its terminal voltage falls as it delivers more current. Voltage regulation expresses that fall: regulation = (V no-load - V full-load) / V full-load x 100 percent. A resistive loading rheostat is the usual way to draw a controlled current from the machine while this is measured.
- Confirm that the source voltage, current, phase and frequency match the rating of the bank.
- With the machine stopped, set the bank to minimum load and connect it to the machine terminals through an ammeter and voltmeter.
- Run the machine to rated speed, adjust it to rated voltage at no load and record this voltage.
- Increase the load in steps up to rated current, keeping speed and excitation constant, and record voltage and current at each step.
- Reduce the load to zero before stopping the machine.
Because the bank turns up to 3 kW into heat, it needs free ventilation, sound earthing, tight terminals and suitable circuit protection, and it should never be covered while in use.

Frequently asked questions
What is voltage regulation and how is it measured?
It is the change in terminal voltage between no load and full load, as a percentage of the full-load voltage. It is measured by loading the machine from zero to rated current at constant speed and excitation.
What safety points apply to a 3 kW loading rheostat?
It dissipates its load as heat, so it needs ventilation, earthing, secure terminals and circuit protection, and its voltage, current and duty ratings should be checked before connection.
