Rata High Voltage Resisitive Load Bank Manufacturer
Product Overview
1) Product overview
Product Features
- Rata’s high-voltage resistive load bank is a containerized, air-cooled test load system designed primarily for high-voltage generator and power-plant applications (example model: RT5000kWLB — 5000 kW, AC 11 kV, 3-phase).
Product Value
- It is engineered for continuous-duty operation, with modular load steps and the ability to parallel multiple units for larger capacities.
Product Advantages
- Available with both local panel switching and remote PC control (Modbus TCP), and built for outdoor deployment and long-term field use.
Application Scenarios
2) Product features
- High power rating and modular steps (example: 5 MW total with 100 kW resolution and defined step groups).
- Forced air cooling with axial fans, horizontal intake/vertical outlet; noise < 80 dB at 3 m.
- Precision loading: ≤ 3% loading accuracy and ≤ 3% 3‑phase unbalance.
- Robust resistors (8020 Ni-Cr alloy finned elements), Q235 powder-coated steel enclosure, and container-type design for outdoor use.
- Multiple protection functions: over-temperature, low-airflow, phase-sequence, short-circuit, fan interlock, access control, humidity/temperature control, emergency stop.
- Control and communication: local panel or remote PC, RJ45/RS232/RS485 interfaces, Modbus TCP compatibility; load data save/print capability.
- Compliance and documentation: CE, ISO9001/14001/45001, detailed factory test report, wiring diagrams, manuals and operation software provided.
3) Product value
- Enables accurate, fast and repeatable load testing of high-voltage equipment (transformers, breakers, generator sets) to validate performance and reliability.
- Reduces commissioning and maintenance downtime by providing a controlled, representative load environment for diagnostics and burn-in.
- Scalable and customizable to customer voltage/power needs (OEM/ODM options for design, color, logo).
- Long service life (typical 20-year design lifespan) combined with comprehensive after-sales support reduces total cost of ownership.
- Enhances safety and compliance by meeting international standards and including multiple protection layers.
4) Product advantages
- High-quality components sourced from first-tier suppliers and collaboration with established partners (ABB, Schneider, Omron, Siemens, Phoenix Contact, Delixi).
- Strong R&D and engineering support from Rata, plus lifelong technical consulting and a responsive after-sales promise (24/7 support, rapid response and site dispatch commitments).
- Flexible control options and industry-standard communications make integration into test automation and plant SCADA straightforward.
- Rugged, containerized outdoor design with continuous-duty capability and parallel expansion for large-scale testing.
- Ready-made documentation, training materials, and remote-operation tools (software and video) for faster operator ramp-up.
5) Application scenarios
- Power system maintenance and commissioning: testing transformers, high-voltage switches, circuit breakers and generator sets (including gas-fired power plants).
- Power engineering, electronic and component testing: verifying resistors, capacitors, inductors and passive components under load.
- Research, teaching and laboratory environments: reproducible load conditions for experiments and training.
- Industrial and OEM maintenance: diagnostics for motors, generators, HVAC compressors, solenoid valves, sensors, semiconductors and lasers.
- Telecommunications, marine and military power set testing where rugged, standards-compliant outdoor load banks are required.
