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 work with different line voltages for single and three-phase circuits. The Power Factor Load Bank is a free-standing and mobileunit. 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. 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. The load bank has smallwheels, for easy mobility. This saves time setting up experiments and clearingthe classroom or laboratory after use. 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.
