Part One
In power station construction and generator O&M projects across Arab regions, generator factory acceptance, on-site load verification, and sudden load change tests are essential procedures to ensure stable and reliable commissioning of the generator units.

Stable & Reliable Resistive Load for Full-Condition Generator Testing

The equipment adopts new power consumption components. Resistive elements are heat-shrink sealed inside stainless steel tubes, fitted with insulating heat sinks externally.

It features excellent moisture and corrosion resistance, high insulation class, and robust safety. With high resistor power density and balanced three-phase current, there is no risk of red-hot air. The independent axial flow fan provides continuous heat dissipation, greatly extending the service life of the whole unit. The matched axial fan delivers large air volume, high heat dissipation efficiency and low operating noise.

Optimized staged power switching design: Power stages: 100kW, 100kW, 300kW, 500kW, 1000kW. Three-phase synchronous switching enables flexible combination of different loads to simulate various actual loading conditions of generators. It accurately verifies the output performance of generator units under varying loads and supports sudden load-on / sudden load-off tests.

Multi-layer Comprehensive Protection System to Ensure Safety of High-Voltage Testing

For high-voltage generator test scenarios:
✅ Load over-temperature protection: When load temperature＞75°C or air outlet temperature＞180°C, audible & visual alarm triggers. If overtemperature persists for 30 seconds, the load stage will be automatically disconnected and unloaded for shutdown.
✅ Overvoltage protection: When voltage exceeds 1.1 times the set value, protection is triggered with forced load shedding after 30 seconds.
✅ Overcurrent protection: When total current exceeds 1.1 times the set value, the protective relay activates and forces load shedding after 30 seconds.
✅ Emergency stop protection: In case of sudden hazards during testing, one-click emergency stop immediately cuts off power to the whole unit.

Dual Control Mode, Local & Remote Host PC Control Supported

RS485 communication interface supports one-click switching between the two control modes.

Local mode: Touchscreen operation for on-site staff to perform local setup, load switching and data reading.

Remote mode: Connect to the host computer system. Customers can independently develop software and integrate it into their own monitoring platform for remote control.

Environmental Adaptability for Operating Conditions in Arab Regions

Operating ambient temperature: -10℃ ~ +50℃, suitable for hot high-temperature site environments in the Middle East.

Maximum applicable altitude: 2500 m, relative humidity ≤90%, seismic resistance grade VIII. The whole unit adopts indoor containerized structure with IP54 protection grade (when door closed in standby status).
