Wuhan Dewei Electrical Test Equipment Co.,Ltd is able to supply variety kinds of test machine for transformers. And our integrated test equipment bench combines single functions into one machine to meet our customers' different test requirement.
Product Description: DWBCT-III transformer test systems is widely used for power supply system, transformer producing company, electrical laboratory etc. It contains many different testing functions in one machine, such as controlling, monitor, testing, protection and so on. With features of easily installation, stable quality and accurately testing datas. We are able to design and produce this testing equipment as per our customer's requirement to make it work automatically, micro-computer control, effective, safely operation. Windows Chinese & English operation interface, automatically collect testing datas, calculating and effect & printing testing reports. The test datas can be stored and printed out for your closer checking. ? Product functions; The following functions can be selectable, and OEM service available if you have any special requirement. Our professional engineers will design and work out some special functions for you if needed. 1. ?Transformer No-load loss measurement(Automatically adjust to rated voltage under non-rated.); 2. ?Transformer No-load current measurement (Automatically calculate no-load current percentage.); 3. ?
