Loading Rheostat 10KW
Product Code : SCL-EAE-11318
Quick answer: The Loading Rheostat 10 kW is a high-power resistive loading rheostat with a stated capacity of 10 kW. It absorbs real power as heat while a generator or alternator is run on load, so students can record load characteristics, voltage regulation, output power and efficiency, and compare loaded with no-load operation. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and technical institutes.

Why machine tests need a high-power rheostat
The power a resistor can safely absorb limits the load it can put on a machine. A bench rheostat rated 100 ohm and 1.6 A, for example, can dissipate at most about 256 W (P = I^2 R = 1.6^2 x 100). Loading a generator to several kilowatts needs a rheostat built for that power, with elements and cooling to match, and the 10 kW rating of this unit places it in that class.
With the rheostat across the generator terminals, the load is increased from zero while terminal voltage, load current and output power are recorded. The resulting load characteristic shows how the voltage falls with current, the regulation follows from the no-load and full-load voltages, and efficiency comes from comparing output with the measured input.
- Confirm the approved voltage, frequency, current, phase, resistance and duty-cycle ratings.
- Place the apparatus in a dry, stable, adequately ventilated area.
- Isolate the supply and connect the rheostat to the machine through the meters.
- Start at no load, bring the machine to rated conditions, then add load in steps and record the readings.

Frequently asked questions
Why can't an ordinary laboratory rheostat load a generator?
Bench rheostats used in circuit practicals are typically rated at a few hundred watts or less. A generator test at several kilowatts needs a loading rheostat built to absorb that power, such as this 10 kW unit.
What results does a 10 kW loading rheostat help obtain?
Load characteristics, voltage regulation, output power and efficiency of compatible generators and alternators, together with a comparison of no-load and loaded operation.
