Air 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.

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.

Crowbar Resistors
-
Crowbar resistors are three phase resistance banks which are connected to the rotor windings of the DFIG (Doubly-Feed Induction Generator) such as wind power generator. They are used to prevent damage to the inverter circuits attached to rotor side when a fault occurs in the grid. DFIG power converter, which has a restricted over-current limit, needs special attention during faults in the grid. If the rotor current or DC link voltage reaches the threshold value, crowbar resistors disconnect the converter in order to prevent the generator turning into a squirrel cage induction machine. By crowbar resistors, the DFIG could stay connected to the grid and continue its operation.

SCR Controlled DC power Supplies
-
Variable DC power supplies are AC to DC power supplies with a variable DC output. The output can be varied with an SCR controller. The AC input power can be single-phase or three phases. With single-phase AC input, the DC output ripple is very high (50%). With three-phase AC input, the DC output ripple is low (5%). This would be a key benefit for selecting three-phase AC input instead of a single phase.
