6kV High Voltage Phase Sequence Indicator,
380V High Voltage Phase Sequence Indicator
The instrument can test voltage 50V-500V and 6kV above, check if the phase sequence is A-B-C for three-phase power source. It is simple to operate and small in size.
1. Red moving lamp means positive phase sequence, green moving lamp means negative phase sequence
2. Applied to 380V low voltage level, also to 6KV High voltage level when matching with insulation rod
3. Auto power switch on/off function
