Voltage-Transformer Circuit Breaker
Overview of Functions
The Voltage-transformer circuit breaker function detects the tripping of the voltage-transformer circuit
breaker due to short circuits in the voltage-transformer secondary circuits.
The Voltage-transformer circuit breaker function works independently of Measuring-voltage failure detec-
tion and should be used – if possible – in parallel to it.
The tripping of the voltage-transformer circuit breaker has an impact on the quality of the recorded measured-
value data (see chapter
3.3 Processing Quality Attributes ).
For the following functions the reaction (block/not block) can be set within the function in cases of a tripping
of the voltage-transformer circuit breaker:
•
Overcurrent protection, phases
•
Overcurrent protection, ground
•
Overvoltage protection with 3-phase voltage
•
Overvoltage protection with positive-sequence voltage
•
Overvoltage protection with any voltage
•
Undervoltage protection with 3-phase voltage
•
Undervoltage protection with any voltage
Structure of the Function
The Figure 8-10 shows the position of the function in the device. Every voltage measuring point contains the
Voltage-transformer circuit breaker function.
