marke Posted August 1, 2004 Report Share Posted August 1, 2004 Hello toprangeKWhr is measured by the use of a rotating disk KWHr meter (or an electronic equivilent). This responds to KW drawn from the supply and accumulates this.KVA is measured by a peak reading ameter that has a slow response. This meter is generally refered to as a MDI or a Maximum Demand Indicator.The KVA is the maximum current times the phase voltage times root three.
