7.4.2 Functionality
SEMOD171457-5 v8
Loss of voltage check (LOVPTUV ) is suitable for use in networks with an
automatic system restoration function. LOVPTUV issues a three-pole trip
command to the circuit breaker, if all three phase voltages fall below the set value
for a time longer than the set time and the circuit breaker remains closed.
The operation of LOVPTUV is supervised by the fuse failure supervision
FUFSPVC.
