چکیده

Customer loads were linear in nature. When a sinusoidal voltage was supplied to them, they drew a sinusoidal current. They typically fell into the categories of lighting, heating, and motors. In general, they were not very sensitive to momentary variations in the supply voltage, such as transients and voltage sags. The loads were not connected together in networks so grounding issues other than safety were not very critical.

Towards Quality of Data Standards: Empirical Findings from XBRL

Certain data standards can help improve the quality of the data created according to the standards. But data standards do not always improve data quality. We introduce the notion of “quality of data standards” and argue that quality of data is affected by the quality of the standards used. We develop metrics for assessing quality of data standards. The metrics are evaluated empirically using co...

Software Implementation of Power Quality Standards

In recent years, equipment and network standards have been increasing in both number and complexity. Two standards that will soon be introduced to Australia are the MV and HV standards for assessing distorting and fluctuating loads, AS/NZS 61000.3.6 and AS/NZS 61000.3.7, respectively. Utility engineers, being under increasing time constraints, are turning more and more to software to quickly so...
