Product
Resistive Load Banks
R Series
-
Load banks are devices which contain resistive, inductive and/or capacitive loads, apply the load to an electrical power source and dissipate the power of the electrical source. Portable and stationary resistive load banks incorporate as low as 1 kW load step increments for testing small to large generating sets. The fine control resolution ensures accurate load control and power factor targeting adjustments.

Air Core Electric Arc Furnace Reactors
-
Arc Furnace Reactors are serially connected reactors that are installed in the supply systems of arc furnace transformers to stabilize arc and limit the unstable arc furnace current and voltage drop which optimize their melting process. These buffer reactors are connected in series to the primary side of the furnace transformer. Typically these reactors are tapped coils and manufactured as per customer'stap requirements.

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.

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.

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.

Sensing Resistors
Resistive Voltage Dividers
-
NGR Sensing Resistors are attached in parallel to the neutral grounding resistor. The sensing resistor allows a protective relay to detect a resistor failure in a continuous manner. Sensing Resistors are used in combination with neutral grounding resistor monitor relays. The relay measures neutral grounding resistance, neutral grounding resistor current and neutral to ground voltage. The relay continuously measures neutral grounding resistor ohmic value in an unfaulted system and it trips on if neutral grounding resistance varies from its calibrated value.
