Function description
Loss of voltage check
Functionality
Loss of voltage check LOVPTUV (27) is suitable for use in networks with an automatic
system restoration function. LOVPTUV (27) 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.
