Yes - I've decided I don't really know what the question is stating as the load condition. Does it mean a load of half the KVA rating with 0.6 power factor or an efficiency of 60% at an unspecified lagging power factor condition? Or perhaps something else ....? It's rather cryptic.(iv) Determine the voltage regulation in percentage for a load condition of half-load efficiency of 0.6 power factor lagging. Draw the phaser diagram.
i don't know how to calculate V.R for half load efficiency..
should i calculate the half load efficiency first?
