7.4.1 Identification
Function description
Loss of voltage check
7.4.2 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.
