The "Network Protection and Automation Guide" (NPAG) is a widely recognized reference book in the field of electrical network protection and control. Before being renamed to Areva, it was known under the brand Alstom, and before that, it was GEC Alsthom. Alstom Group re-acquired AREVA T&Ds Transmission activities in June 2010 and changed its business name from AREVA T&D Ltd. to Alstom Grid Ltd. In June 2010, Alstom and Schneider Electric signed an agreement with Areva for the acquisition of Areva T&D, its transmission and distribution business.
The Network Protection and Automation Guide originally published in 1966. It has undergone thourh several editions from then on incorporting the latest technology available. The last published by Alstom was in 2011. With the acquisition of Areva T&D by Schnieder Electric, the publications of the Network Protection and Automation Guide has been taken over by Schneider Electric.
This book covers principles and applications of protection relays and automation systems in electrical networks. It provides a comprehensive overview of protection techniques, relay settings, fault calculations, and more. Below is a list of topics contained in the latest version of the NPAG.
