Schneider Electric Cahiers Techniques

Schneider Electric Cahiers Techniques – A collection of documents intended for engineers and technicians

Cahiers Techniques is a collection of documents intended for engineers and technicians, people in the industry who are looking for more in-depth information in order to complement that given in product catalogues. Furthermore, “Cahiers Techniques” are often considered as helpful “tools” for training courses.

Schneider Electric provides knowledge on new technical and technological developments in the electrotechnical field and electronics. They also provide better understanding of various phenomena observed in electrical installations, systems and equipment.

Each “Cahier Technique” provides an in-depth study of a precise subject in the fields of electrical networks, protection devices, monitoring and control and industrial automation systems.

About Schneider Electric

Schneider Electric SA. The Group’s principal activities are electricity and automation management. The Group operates under three major segments:

• Electrical distribution
• Automation and Control
• Secured energy

Electrical Products

Under Electricity distribution, the Group offers electrical products such as circuit breakers, switches, safety lighting, prefabricated busbar trunking, modular switchgear, Power Line Carrier communication networks and Voice-Data-Image solutions. Under Automation and Control, the Group offers products to control and supply power to equipment such as contactors, overload relays, soft starters, speed drives, sensors and operator terminals.

Schneider Electric also offers configuration, programming and operating support software, communication networks and field buses. Under Secured energy, the Group offers APC’s UPS systems.

Schneider Electric operates mainly in Europe, Asia Pacific and North America. In 2008, the Schneider Electric acquired ECP Tech Services, Marisio, Wessen, RAM Industries, Xantrex and American Power Conversion (APC).

In past 20 years Schneider Electric released around 70 technical publications related to electricity and automation, and these publications are listed below.

All documents, EE software and EE books are free to download.
