Beemet Power Factor meters are used to monitor changing power factor conditions on irreversible balanced load systems.
The moving coil indicators PF 72/96/144 and a phase angle adjuster are used to monitor changing power factor conditions on ir-reversible balanced load systems & Unbalanced System. The power factor is indirectly determined by measuring the phase angle between current and voltage (both sinusoidal). However the indicators are calibrated in values of cos ö of the angle ö . These meters offer several advantages in Switchboard & Generating Set panels. Number of meters can be mounted in a single Cut out(Mosaic Mounting). The Bezel, Front window glass and Dial can be easily replaced.
• Knife edge pointer.
• Glass filled polycarbonate housing.
• Easily replicable glass and bezel.
• Easy installation with swivel screws.
