Radiator Mounted Load Banks
RD-Series
-
RD-series radiator mounted load banks are designed to be fitted directly onto diesel generator sets. RD-series load banks use the engine cooling air from the generator radiator to cool the load elements.

Inductive Load Banks
L-Series
-
L-series inductive load banks are devices which contain inductive loads, apply the load to an electrical power source and dissipate the reactive power of the electrical source. L-series load banks are designed for portable and fixed applications. Hilkar brand L-series load banks have robust design and are specifically designed for corrosive environments. Load banks can be controlled via local, remote, wireless remote or automatic control systems.

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.

LV Iron Core Shunt Reactors
-
Iron core Shunt Reactors act as an absorber of reactive power to increase energy efficiency of the power system. Shunt Reactors 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. Shunt Reactors can be directly connected to the power line or to a tertiary winding of a three-winding power or distribution transformer.

Air 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.

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.

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.
