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

Sifam Tinsleys功率因數(shù)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.

采用動(dòng)圈指示器和相位角調(diào)節(jié)器來監(jiān)測(cè)不可逆平衡負(fù)載系統(tǒng)的功率因數(shù)變化情況。

功率因數(shù)是間接地通過測(cè)量相角φbetween電流和電壓(正弦)。然而指標(biāo)校準(zhǔn)值的余弦角φ。這些儀表在配電板和發(fā)電機(jī)組上提供了一些優(yōu)勢(shì)。可安裝在面板上的米數(shù)(馬賽克安裝)。面板、玻璃和表盤可以輕松更換。
