A Quality Information System Based on Distributed Data Aquisition

E-mail Print PDF

Peter G.V. Axelberg

Traditionally the control and supervision of a power network has mainly been focused on the operation of the network or for protecting system components during fault conditions etc. Relatively little attention has been focused on the product itself - the electrical energy. This old approach is now changing...
