The Power Factor Load Bank is a free-standing and mobileunit. It gives predictable load and power factor characteristics, useful formany different power systems experiments. It also helps to show the principlesof a static VAr compensator used in industrial plants and large factories. Theload bank provides three separate inputs: Lines 1, 2 and 3. This allows it towork with single and three-phase circuits. Each line is independent, whichallows it to connect with the others as a star or delta load. The load bankincludes three separate banks of resistive, inductive and capacitive loads.They give a choice and combination of types of loads to give unity and leadingor lagging power factor. A voltage-selector switch allows the load bank to workwith different line voltages for single and three-phase circuits. Each bank maybe set to different values, to give an unbalanced load for balanced andunbalanced load tests. The top of the load bank includes a useful worktop forany additional instruments or for recording results. The load bank has smallwheels, for easy mobility. This saves time setting up experiments and clearingthe classroom or laboratory after use.
