Sigma Series LML Meter

Sigma Series LML Meter

 

The Watt and Var meters, LML 96 are offered for

single phase,
3 phase balanced load 3 or 4 wire,
3 phase unbalanced load 3 or 4 wire AC Systems
These instruments are suitable to indicate forward (export / out going) and reverse (import/in coming) power flow as well as inductive and capacitive reactive power. They can be used both on sinusoidal and non-sinusoidal current These meters offer several advantages in Switchboard & Generating Set panels. Number of meters can be mounted in a Panel Cut out (Mosaic Mounting). The Bezel, Front window glass and Dial can be easily replaced
