AC400-550kW Adjustable Load Bank In 3 phase 4 wire With Frequency 50 HZ
Introduction
(1) This system, which is of independent research and development of electricity load test equipment by our technology, combining dry load module with the automatic measurement and control module, can accurately detect all kinds of generator output power and load capacity, full load and overload test.
(2) The system consists of 1 sets of 500kW Resistive load bank. The System is made up of two parts of measurement and control and load, mainly including AC dry load, automatic data acquisition system, automatically loading and unloading control system, the cooling device, auxiliary control, PC software and so on.
Application
1. Ups system testing
2. Load optimization in prime power applications
3. Factory testing of turbines
4. factory testing of engine generator sets
5. To reducewet stacking problems
6. Periodic excercising of stand-by engine generator sets
