Line monitoring with SIRIUS 3UG4 relays (digital)

The 3UG4 monitoring relays provide a maximum degree of protection for mobile machines or systems and unstable lines. It detects phase failure, phase sequence, phase asymmetry and under-voltage. The training movie shows the analog setting options and demonstrates the functionality of the 3UG4513 using the example of phase failure and sequence.
