Load banks apply controlled electrical loads to power sources. Resistive elements convert active power into heat, while inductive and capacitive elements exchange reactive power with the source.
Unlike variable field loads, load banks provide predetermined and adjustable loading conditions, enabling reliable testing, commissioning, and performance verification of electrical power systems.
Hilkar RD-Series radiator-mounted load banks are designed for direct installation on diesel generator sets. They utilize the generator radiator’s cooling airflow to dissipate heat from the load elements, eliminating the need for a separate cooling system.
Available in portable and stationary configurations, RD-Series load banks provide load step increments as low as 1 kW, enabling precise load control and accurate performance testing of small to large generator sets.
Suitable for both workshop and on-site testing, RD-Series load banks can also be supplied as trailer-mounted units for flexible field applications.
- Robust and durable design
- Vertical or horizontal air discharge configuration
- Integrated remote control system with data acquisition, monitoring, and load step control
- Easy integration and synchronization with other load banks
- Corrosion-resistant coating for outdoor applications
- Vibration-resistant stainless steel resistors
- Designs compatible with IEC 62116, IEEE Std 929, and UL 1741 standards
Hilkar load banks can be equipped with optional touchscreen LCD displays, wireless remote load step controllers, and PC-based control software for advanced testing and monitoring. The control system provides fan start/stop control, electrical parameter monitoring, load step management, timing functions, data recording, test modes, and fault detection. PC controllers communicate with the load bank via a USB connection.
Load banks include circuit breaker protection and provide easy access to switchgear compartments and load elements. Integrated safety functions protect against fan failure, low airflow, overvoltage, overheating, and phase sequence faults. Designed for permanent integration with generator radiator systems, RD-Series radiator-mounted load banks provide reliable solutions for generator testing during operation and commissioning.
