As the energy hub of the Middle East, Saudi Arabia imposes stringent reliability requirements on high-power generating units in various applications such as oil fields, industrial facilities, infrastructure projects, and emergency power supply systems. The entire lifecycle of generating units—including factory acceptance testing, field commissioning, regular maintenance, and fault diagnosis—must undergo comprehensive performance validation under actual load conditions.



The VILVA AC400V1500kVARL resistive-inductive load bank, featuring integrated resistance and inductance capabilities, high precision, superior safety, heat and dust resistance, and intelligent control, has become the standard equipment for generator testing in the Saudi market, providing reliable testing assurance for power safety and project delivery.




Professional configuration, precisely tailored to Saudi Arabia's testing requirements


Rated Parameters and Load Structure

Rated capacity: 1500 kVA; resistive load: 1200 kW, inductive load: 900 kvar

Rated voltage: AC 400 V, frequency 50/60 Hz, power factor adjustable to 0.8 or 1

Three-phase balanced load condition, designed to simulate typical inductive loads such as industrial motors, pumps, and compressors used in Saudi Arabia.




Core Hardware and Manufacturing Processes

Resistive load: sealed stainless steel tube resistance, moisture-resistant, corrosion-resistant, with high insulation performance, no red heat emission, and long service life.

Sensitive load: High-silicon oriented silicon steel reactor with F/H-grade insulation, featuring low losses and excellent heat dissipation.

Forced air cooling system: High-volume axial fan with bottom-inlet and top-out configuration, operating continuously at full load under stable conditions

Four-layer safety protection against overheating, overvoltage, overcurrent, and sudden stop; automatic disconnection in case of abnormalities

Power levels are finely adjustable and support transient load testing with sudden loading/unloading.

Display real-time parameters such as voltage, current, power, power factor, and frequency




environmental suitability

Operating temperature: -10°C to +55°C, perfectly suited for Saudi Arabia's summer high-temperature conditions.

It can operate continuously, making it suitable for prolonged acceptance and aging tests.



2.Creating core value for Saudi Arabia's power testing initiatives

Simulated real-world conditions for more reliable test results

The integrated resistance-inductance load accurately replicates the power consumption characteristics of Saudi industrial environments, comprehensively verifying a generator's capabilities in voltage stabilization, frequency regulation, voltage adjustment, excitation control, and load operation, thereby eliminating performance misjudgments associated with no-load or purely resistive testing.


High-temperature dust conditions maintain stable operation and reduce the failure rate.

With high-temperature resistance, IP54 protection, and a robust wind-cooling design, the equipment ensures reliable long-term operation in Saudi Arabia's extreme conditions without performance degradation, overheating, or short circuits, delivering extended service life and reduced maintenance requirements.


High security level, ensuring protection for both personnel and equipment.

Multi-layer protection, independent emergency stop, delayed heat dissipation, and mandatory grounding safety specifications eliminate risks of overload, overheating, and electric shock, meeting stringent safety standards for oilfield and industrial applications.


Efficient testing, faster delivery

Touchscreen one-click loading, precise categorization, and automatic recording significantly reduce debugging time; supports remote centralized control, ideal for parallel testing and batch acceptance of multiple units.




Data Standards: Enabling Compliance Verification

With precise parameters and comprehensive records, it meets the acceptance requirements of Saudi Arabia's power industry, supports report generation and project registration, and enhances delivery compliance rates.




Addressing the key challenges in generator operation


The generator lacks sufficient power under load, resulting in inadequate actual output.

Avoid the following issues with generators: normal performance under no-load conditions, significant voltage drop upon load connection, insufficient power output, and inability to drive motors or equipment.




When a generator is connected to an inductive load, the voltage becomes unstable and the frequency fluctuates.

Prevent voltage fluctuations, frequency drift, and excitation abnormalities during operation of oil fields and factories, which could cause equipment tripping and production interruptions.



3. The generator experiences excessive temperature rise under high-temperature conditions, automatic capacity reduction, and sudden shutdown.

Ensure continuous operation under full load at Saudi Arabia's high temperature of 50°C without triggering alarms, overheating, or protective shutdowns, while maintaining stable and reliable power supply.



4. Hidden faults in generators cannot be detected in advance and require frequent maintenance after commissioning.

Identify potential issues related to heat dissipation, insulation, control systems, and output performance in advance to prevent on-site failures, operational downtime losses, and substantial maintenance costs.



The VILVA AC400V1500kVARL inductive load bank features a professional load design, extreme environment compatibility, multiple safety safeguards, and intelligent, efficient operation, fully meeting generator testing requirements for Saudi Arabia's oil fields, industrial applications, infrastructure projects, and emergency power systems.



It not only enhances test accuracy and safety, but also reduces operational costs and accelerates project delivery, providing critical support for the stable operation and high-quality development of Saudi Arabia's power system.
