Sifam Tinsleys Power Factor Meter (LF 72 / LF 96)

Sifam Tinsleys功率因数表(LF 72 / LF 96)

The moving coil indicators and a phase angle adjuster are used to monitor changing power factor conditions on ir-reversible balanced load systems.

The power factor is indirectly determined by measuring the phase angle φbetween current and voltage (both sinusoidal). However the indicators are calibrated in values of cosine of the angle φ. These meters offer several advantages in Switchboard & Generating Set panels.Number of meters can be mounted in Panel Cut out (Mosaic Mounting).The Bezel, glass and dial can be easily replaced.

采用动圈指示器和相位角调节器来监测不可逆平衡负载系统的功率因数变化情况。

功率因数是间接地通过测量相角φbetween电流和电压(正弦)。然而指标校准值的余弦角φ。这些仪表在配电板和发电机组上提供了一些优势。可安装在面板上的米数(马赛克安装)。面板、玻璃和表盘可以轻松更换。
