1.2 Nomenclature
Due to the technical nature of this manual, many special terms, abbreviations and
acronyms are used throughout the manual. Some of these terms are well-known
industry-specific terms while others may be special product-specific terms used by
GE Grid Solutions. The first instance of any acronym or term used in a particular
chapter is explained. In addition, a separate glossary is available on the GE website,
or from the GE contact centre.
We would like to highlight the following changes of nomenclature however:
British English is used throughout this manual.
