The innovated tool set ELF 2 is used to determine phase order in low voltage networks (230/400V) with continuous uninterrupted operation. The set contains two devices for sending and receiving of synchronization signals. Booth devices are powered directly from the measured network and do not need any additional setup to cooperate. With one sending unit, multiple receivers can cooperate at once. The correct operation is indicated with LED diodes. 

Characteristics

• For phase identification in low-voltage power distribution grids
• Based on transmission of synchro- pulses between transmitter and receiver over power line
• Both units powered from measured line
