As an essential tool in power system testing, equipment commissioning, and other work, the portable load bank is highly favored by engineers due to its convenience and practicality. However, to ensure it always maintains excellent working condition and extends its service life, standardized and meticulous maintenance is indispensable. The following are the key maintenance precautions for portable load banks.

In the context of the rapid development of modern industry and technology, the performance testing and operation maintenance of various electrical equipment have become increasingly important. As a high-precision and adjustable simulated load device, the rack-mounted load bank is widely used in multiple fields due to its compact size, convenient installation, and diverse functions. The following will elaborate on the main application scenarios of the rack-mounted load bank.

During the operation of numerous devices, heat dissipation and load management are the key factors to ensure the stable and efficient operation of the devices. As an advanced device, the liquid cooling load bank plays a significant role in multiple fields and has many remarkable advantages.

In the field of power electronics, the load bank is an important device used to simulate the load characteristics of circuits. According to the differences in their working principles and load characteristics, they can be divided into resistive load bank and capacitive load bank. These two devices play different roles in the circuit. The following will elaborate on their differences in detail from multiple key aspects.

Capacitive load bank, as key equipment for simulating capacitive loads in power systems, play an irreplaceable role in multiple fields due to their characteristic of providing capacitive reactive power. The following will provide a detailed introduction to its specific applications in scenarios such as power system commissioning, new energy equipment inspection, and industrial automation.

Inverter performance testing: By connecting to a resistive load bank, the equivalent resistance characteristics of the power grid are simulated to test the inverter's efficiency under different power outputs (such as verifying a conversion efficiency of over 95%), voltage/frequency stability (such as output voltage fluctuation range ≤±5%), and harmonic content (THD must be ≤5%). For instance, before the inverter leaves the factory, it needs to undergo full-load continuous operation tests through a resistive load bank to ensure that it does not overheat or have abnormal output during long-term loading.

During the testing and operation of power electronic equipment, resistive load bank, with their stable resistive characteristics, have become an important tool to ensure the safe and efficient operation of the system. Its application scenarios are widely distributed across multiple industries. The following will elaborate on its specific applications in detail from different fields.
