General Introduction
Kaixiang Load Bank can simulate the real working conditions and provides a rigorous test regime for power supplies from 1kW to 60MW. Resistive, inductive(reactive),capacitive or combined load banks can be customised for any application. They can be used for testing numerous sets in a workshop environment, or used for on-site commissioning, witness tests and proof trials.
Custom-built load banks can be supplied for most powers, voltages, frequencies and sizes. Multi-voltage load banks are also available for operation over a large voltage range. At the same time, It can operate in parallel with more than two units.
Kaixiang Load Bank are available in stationary type for permanent installation or portable type with fork lift pocket base, castors. Larger load banks, typically above 1250kVA, are based on an ISO container construction. Special finishes including custom paint colors and stainless steel casings can be supplied.
Application
Large generator system testing in ocean engineering, drilling facilities,ship construction etc field
Factory testing for generator, static voltage characteristic test, speed characteristic test;
Marine generator overload protection test,parallel operation test,reverse power and reverse current protection test
Assist shipyard in mooring test,sea trial test
Assist with the acceptance of the vessel generator test
Eliminate the carbon deposition of generator
As the generator loading system
Periodic running test for standby generator
UPS inspection and maintenance
Ship battery charging/discharging system testing
The acceptance of new system and testing of servicing equipment
Advantage:
The ability to test critical power systems at voltages of 1.2KV to 80kV using direct-connect, High Voltage Load Bank offers engineers flexibility, time savings, cost savings, space savings and simplicity. It mainly used to commission utility, oil & gas, and industrial power systems without the need for additional transformers and cabling.
