Product
Air Core Motor Starting Reactors
-
Motor starting reactors are used to reduce voltage during starting of large 3 phase motors while limiting inrush currents.

Product
Harmonic Filter Resistors
-
The widespread use of nonlinear loads such as power electronics based equipment and electric arc & ladle melt furnaces all around the world hinder the quality of electric power. One of the most important parameters for defining the power quality is harmonic distortion.

Product
dv/dt Filters
-
dV/dT Output Filter Modules effectively protect motors against these high voltage spikes due to the use of motor cables between IGBT based motor drives and motors.

LV Iron Core Harmonic Filters
-
Nonlinear loads such as power electronics based equipment and electric furnaces are sources of harmonic currents leading to harmonic distortion, which is one of the most important parameters for defining the power quality. Most of the commercial loads such as personal computers, photocopy machines, power supplies, and compact fluorescent lamps; and industrial loads such as AC and DC motor drives inject harmonic currents into the network that they are connected to.

LCL Filters
-
LCL Type Harmonic Filter Modules are used to filter out the input current harmonics of the Motor Drives having six-pulse diode/thyristor rectifiers, where harmonic current distortion exceeds the limits defined in standards.

Motor Termination Units
-
Since the rise time of IGBTs are in the range of a few tens of nanoseconds (between 50ns-200ns), even short cables between PWM motor drives and motors cause voltage doubling at the motor terminals due to Travelling Wave Phenomenon as in transmission lines. The insulation of motor windings are prone to failure due to high voltage spikes if necessary precautions are not sufficiently taken. RC Type Output Filter Modules reduce these high voltage spikes to protect motors by connecting to stator terminals.

Grounding Transformers [ZN (Zigzag), ZNyn, YNd(open), Ii0]
-
Grounding Transformers are designed for providing an artificial neutral point for ungrounded three phase power systems. During the line-to-ground faults, grounding transformers provide an easy path to ground faults to limit the fault currents and transient overvoltages.

Explosion-Proof Heaters
-
Explosion-Proof Heaters (ATEX certified) provide neutral convection solutions of heating for electrical equipments in hazardous industrial locations where potential for explosion exists due to the presence of flammable gases, vapors, powder-metals or dusts.

Product
Dynamic Braking Resistors
-
Speed of three phase asynchronous squirrel-cage motors and three phase synchronous motors are generally controlled by motor drives where frequency of the drive output determines the motor speed, and it can be adjusted without dependence on the voltage magnitude.

Iron Core Current Limiting Reactors
-
Current Limiting Reactor (CLR) is one of the most effective short circuit current limiting devices. It reduces stresses on busses, insulators, circuit breakers and other high voltage devices. Use of CLR is the most practical and economical approach at current limiting.

Product
Motor Starting & Control Resistors
-
Motor Starting Resistors are used to reduce the voltage at the motor terminals and also decrease the starting current. Motor Starting Resistors are necessary because the self resistance of a motor armature is very low. When the voltage is first applied, excessive current will flow. For limiting this current, since there will be no resisting back electromotive force (emf),some series resistance can be added to the armature windings.

Air Core Shunt Reactors
-
Shunt Reactors act as absorbers of reactive power to increase energy efficiency of the power system. Shunt Reactors are inductors that are used in order to compensate capacitive reactive power generated by long and lightly loaded transmission lines as well as underground cables, thus allowing the flow of more active power through the system and avoiding over voltages. The shunt reactors provide inductive compensation.

LV Iron Core Smoothing Reactors
-
Smoothing Reactors are serially connected reactors inserted in DC systems to reduce harmonic currents and transient over currents and/or current ripples in DC systems. They are necessary in order to smooth the direct current wave shape to reduce losses and improve system performance.
