SONEL PHASE SEQUNCE TESTER

Designed for testing three-phase power installations in the range of phase-to-phase voltages from 100 to 600 V. The meter is powered from the measured installation (no separate power supply is required). The device shows the presence of voltage in all phases; monitors the symmetry of all voltages and the absence of symmetry and determines the correctness of the phase sequence. All results are reflected through bright, highly visible LEDs.
