Nalder Lipman Moving-iron Power Factor Meter

Nalder Lipman Moving-iron Power Factor Meters are more efficient in working as compared to electrodynamic power factor meters. These power factor meters are used on a three-phase supply. Its construction and working are very simple. So, the construction and working of this power factor meter are written below:

Construction

Ā Its moving system holds threeĀ iron elements. These three elements carry iron cylinders. These elements are mounted on a shaft and these are separated from one another withĀ non-magnetic distance pieces. The shaft carries theĀ damping vanesĀ and aĀ pointer. These three elements are at 120 degrees to each other. Each iron element is magnetized with its individualĀ voltage coilsĀ named B1, B2 and B3. These are connected in a star connection with the supply lines. The two parallel F1 and F2 of a single current coil is connected on a line of supply.

Working

The whole system is free to move between the two parallel halves. These meters read the power factor directly from the supply. The phase angle Ļ† is produced in a moving system. The deflection Ī˜ is equal to phase angle and the pointer deflects on a scale.

Advantages

This instrument is not affected by the variations in voltage and in waveforms inĀ the power supply.

A rotatingĀ magnetic fieldĀ is not produced so the moving system deflects properly.
