Loading Rheostat 12KW
Product Code : SCL-EAE-11303
Quick answer: The Loading Rheostat 12 kW is a variable resistive loading unit with a rated capacity of 12 kW. Changing its resistance varies the current drawn and so the load placed on a generator, motor or test circuit, for load characteristic, efficiency and regulation experiments. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and universities.

How the loading rheostat is used
A loading rheostat is a large variable resistor built to absorb power. Connected across the output of a generator, it sets the current drawn: lowering its resistance increases the current and hence the electrical load. The power it absorbs, P = I^2 R, is dissipated as heat, and the 12 kW rating is the most power the unit is intended to absorb.
Typical experiments include the load characteristic of a DC generator, where terminal voltage is plotted against load current; loading a DC motor through a coupled generator; and efficiency and regulation tests in which input and output power are compared at several load settings.
- Check that the rheostat's current, voltage and power ratings suit the machine under test.
- Set the unit on a bench or floor position with space around it for heat to escape.
- With supplies off, connect it to the machine output through an ammeter and voltmeter.
- Start at maximum resistance (minimum load), run the machine up to rated speed, then reduce the resistance in steps and record readings at each step.
