Phase Sequence Meters
-
Phase sequence meter is used for detecting the sequence of the supply in three-phase electric circuits. Since the direction of rotation of three phase electric motors can be changed by changing the phase sequence of supply. And also the correct operation of measuring instruments like 3 phase energy meter and automatic control of devices also depend on the phase sequence. Different types of phase sequence testers are available in today’s market like contact or non contact, static or rotating, etc., in a wide range of voltage or power ratings.

Three-Phase Converters
SIRIO 3PH 7 ALFA 3PHSAP
-
The three-phase converter is an electronic equipment able to vary the RMS value of a sinusoidal voltage by controlling no. 6 controlled, antiparallel-connected conducting diode pairs.Since the wave form is symmetrically split both into positive and negative halfwave, the output voltage average value is not affected and equal to zero. This means that three-phase loads can be fed without gene rating inside the mesh a circulating current with average value other than zero.Moreover, the three-phase converting is obtained with only one control circuit thus ensuring balance between the three linked voltages applied to the load.

LV Iron Core Line & Load Reactors
-
Line and load reactors are generally serial-connected to the input and/or output terminals of three phase equipment such as motor speed controllers, inverters and UPS systems. These equipment make use of semiconductor switches such as IGBTs, thyristors, and diodes and therefore create harmonic distortion and high switching over-voltages (dv/dt). Use of such equipment has been becoming more widespread as the technology advances. However, the negative effects of these equipment should not be overlooked.
