The fuel cell test load is an electrical load used to simulate the actual working conditions of the fuel cell.

It is crucial to the performance evaluation and optimization of the fuel cell. To determine whether the fuel cell test load is damaged, a comprehensive evaluation can be conducted through the following aspects:

The future development trend forecast of load banks mainly includes intelligence, modularization, precise detection, environmental protection and energy saving, and multifunctionality.

In recent years, with the global emphasis on renewable energy and the continuous advancement of technology, the new energy industry is developing at an unprecedented speed. As an important part of new energy, the stability and safety of distributed power generation systems such as wind power and solar power are directly related to the operating efficiency and reliability of the entire system. As the scale of grid connection continues to expand, higher requirements are also placed on the safe and stable operation of the power grid. These not only affect the stability of the power system, but also bring many confusions and challenges to new energy equipment manufacturers and users.

With the rapid development of the big data industry and the AI industry, data centers (IDCs) have become an important infrastructure closely related to the international emerging economy and the daily lives of residents.

Energy feedback to power grid type electronic load bank is based on PWM bidirectional rectification circuit and wide-range voltage converter, which can feed the energy lost by load back to the grid, reducing the energy waste in battery testing.

During the operation of the equipment, single-phase grounding is the most common fault. When arc grounding occurs at the fault point, the insulation damage of the stator winding will be further expanded and even the iron core will be burned and sintered. If it is not discovered and removed quickly in time, the fault will develop into a phase-to-phase or turn-to-turn short circuit.

Resistive load bank (AC Load Bank, Dummy Load Bank, Generator Load Bank, Load Bank for Generator Testing) is a device which can simulate the real-life resistive loads and provides a rigorous test regime for power supplies from 1kW to 60MW. The “load” of a resistive load bank is created by the conversion of electrical energy to heat by power resistors. It mainly used to test and maintenance of Engine Generators, Storage Battery Systems, UPS Systems, Inverters, Ground Power Units, Auxiliary Power Units, Aircraft Power Generators, Wind Generators, Hydro Generators etc.

The operating temperature and humidity range of the load bank will vary depending on the type, application scenario and manufacturer. The following introduces the common range for you:

Choose a suitable load type according to actual needs, such as resistive load, inductive load, capacitive load, etc. Different types of loads have different effects on the equipment, and need to be selected according to the actual scenario of the test or application.

Determine the load type according to the actual test or application requirements, such as resistive load, inductive load, capacitive load or comprehensive load. If you are testing purely resistive devices such as heating wires, incandescent lamps, etc., choose a resistive load bank; for testing inductive devices such as motors and transformers, you need to use an inductive load bank or a comprehensive load bank.
