Functions 2.6 Motor Protection 2.6.2.1 Description General The rotor temperature of a motor generally remains well below its maximum admissible temperature during normal operation and also under increased load conditions. However, high startup currents required during motor startup increase the risk of the rotor being thermally damaged rather the stator, due to the short thermal constant of the rotor.
Page 100 Functions 2.6 Motor Protection Although the heat distribution on the rotor bars may severely differ during motor starting, the different maximum temperatures in the the rotor are not pertinant for motor restart inhibit (see Figure 2-34). It is much more important to establish a thermal replica, after a complete motor start, that is appropriate for the protec- tion of the motor's thermal condition.

Page 226 Functions 2.18 Breaker Control Control Logic using CFC For bay interlocking, a release logic can be created using CFC. Via specific release conditions the information "released" or "bay interlocked" are available (e.g. object "52 Close" and "52 Open" with the data values: ON/ OFF).
Page 227 Functions 2.18 Breaker Control Commands that are initiated internally (command processing in the CFC) are not subject to switching authority and are therefore always "allowed". Switching Mode The switching mode determines whether selected interlocking conditions will be activated or deactivated at the time of the switching operation.
Page 228: Command Logging
Functions 2.18 Breaker Control Device Status Check (set = actual) For switching commands, a check takes place whether the selected switching device is already in the set/ desired position (set/actual comparison). This means, if a circuit breaker is already in the CLOSED position and an attempt is made to issue a closing command, the command will be refused, with the operating message "set condition equals actual condition".
Page 229 Functions 2.18 Breaker Control Commands and information feedback are also recorded in the event list. Normally the execution of a command is terminated as soon as the feedback information (FB+) of the relevant switchgear arrives or, in case of commands without process feedback information, the command output resets and a message is output.

Current Transformer Requirements The requirements for phase current transformers are usually determined by the overcurrent time protection, particularly by the high-current element settings. Besides, there is a minimum requirement based on experi- ence. The recommendations are given according to the standard IEC 60044-1. The standards IEC 60044-6, BS 3938 and ANSI/IEEE C 57.13 are referred to for converting the requirement into the knee-point voltage and other transformer classes.
