UK3F controls:
• voltage values in each phase of the network;
• the order of the phases of the network.
UK3F provides:
• formation of a "Fault" signal in the form of opening normally closed contacts of the "U" opto-relay at a reduced voltage in any phase of the network below a predetermined threshold;
• generation of the “Fault” signal in the form of opening of the normally closed contacts of the “Phase” opto-relay in case of violation of the order of the phases of the network.
