Abstract
The system the intercomparison of unlike impedances of IEN, based on the three-voltmeter method and four-terminal pair definition of the standards, has now been provided with a new direct-digital synthesis generator, having multiple outputs, isolation among the channels, and high amplitude and frequency stability. Experimental results in the new and old configuration are shown and compared.
