The characteristic curves of impedance magnitude and angle as functions of frequency are illustrated below. Customers with the same priority will be ranked by the amount of kVA load in the zone. Duration Enter the duration of the outage as hh: A factor defined for four years is applied in each of those years, not once over the span of four years. If no solution is found within the allowed number of iterations: All network feeders, synchronous and asynchronous machines are replaced by their internal impedances.

Step 3 All loads must be connected downstream of one or more metering locations. In the workspace canvasedit the symbol using the available tools.
