Functional description

5.1.1.

Functions of the machine terminal

The functions of REM 54_ machine terminal are categorized as:

• protection functions
• measurement functions
• control functions
• condition monitoring functions
• communication functions
• general functions
• standard functions

The functions are further divided to two subsets that correspond to different
functionality levels (refer to section “Ordering Information” on page 95).

5.1.1.1.

Protection functions

Protection is one of the most important functions of the machine terminal. The
protection function blocks (e.g. NOC3Low) are independent of each other and have
their own setting groups, data recording, etc. The non-directional overcurrent
protection, for example, includes the three stages NOC3Low, NOC3High and
NOC3Inst, each with independent protection functions.

Either Rogowski coils or conventional current transformers can be used for
protection functions based on current measurement (overcurrent). Correspondingly,
voltage dividers or voltage transformers are used for protection functions based on
voltage measurement (overvoltage).

The protection function blocks are documented on the CD-ROM Technical
Descriptions of Functions.
