Transient Recovery Voltage

Figure A.16 shows the Transient Recovery Voltage scheme. (Reprinted
from Reference 2. Permission granted by Marcel Dekker, Inc.)

When the current through the circuit breaker is interrupted, the entire
system adjusts to its new operating state. The voltage transients produced
separately by the left subsystem, V

L

(t), and the right subsystem, V

R

(t),

stress the recently conducting arc plasma. The transient recovery voltage
(TRV) is defined as the difference between the voltage on the left and
right sides of the circuit breaker.

Figure A.16 Transient Recovery Voltage Scheme

When the basic interrupter of the circuit breaker does not meet the
interruption requirements, auxiliary devices, including an insertion
resistor, shunt capacitor or open-gap grading capacitor, are used to
modify the TRV.
