electronic power banks 271kVA inductive load bank for generator
testing
Introduction
According to the special requirements of users on site, in the agreement the technical standards of AC415-271kVA-RLC Automatic Load Bank and its accessories are proposed including their function, performance, usage, structure, installation and test to provide users with a high efficient and reliable choice, in order to meet the need for generator load test.
All the schematic diagrams of this agreement are for reference only please in kind prevail.
Applications
1 System can work with PC software to realize intelligent operation, automatically finish the parameters testing, and create testing data table, curves and reports that can be printed, reduce a lot of manual operation.
2 System can load power in rated range, measure generator steady-state 3 phase voltage, current, active power, power factor, frequency, and running time, and simulate the generator set real load working state. Power input using sectional type, energy dissipation type load, forced-air cooling, 3 phase fan decentralized supply air, air-flow is sufficient and low noise.

Comprehensive Protection Function: multiple protection, like over temperature, smoke. When in danger, automatically terminate the test and give alarm to protect safety of personnel and equipment.
Stable Running: with the latest generation control module as the core, a sharp rise in system response speed and anti-interference performance, avoid function failure in complex electrical environment, and ensure system running stably and reliably.
New Load Bank Technology: using the international advanced AC load bank technology, overcome the old water bank defects, such as bear bumpy, unable to use when go to sea, realize Mooring Trial and Sea Trail, and simulate the real working condition of generator running.
Mature Manufacturing Technology: load element using excellent anti-corrosion materials; waterproof insulation container packaging, suitable for adverse environment such as ocean. Internal layout is reasonable, air channel is clear, rapid heat emission, and satisfy continuous working need.
Accurate Data: with high precision data collection module and measuring meter, related equipment has passed the certification by CMA (China Metrology Accreditation) qualification testing institution, and ensures the reliability of data.
Flexible Control Mode: based on different using habit, several control modes as following can be choose, local panel operation, remote box controlling, and intelligent software.
Intelligent Loading: after setting generator rated power in software, system realize rapid loading through preset proportion, automatically and continuously load multiple power value and common tests, like stepping, full load, and over load, so that improve working efficiency.
High Efficiency Data Management: display real-time testing data, generate curves graphs automatically, also can put data into storage. According to generator set No. set up testing file, support to query at any time, and improve data management efficiency.
