AL323 Synthetic Tester of Volt-ampere Characteristics
Implementation of standards.
JJG1021-2007
Owing to the ever-increasing demand for relay protection, test and inspection on volt-ampere curve and 10% error curve of AC mutual inductor have arose the attention of power system more an more, and for reason of that, our company self-developed a new generation of AL323 volt-ampere characteristics tester based on extensive opinion from user, which is controlled by high speed single chip microcomputer, with voltage booster inside, making possible the onsite auto-test of CT volt-ampere characteristics and mutual inductor ratio and polarity through single computer. 1A mutual inductor of 500kV is measurable when special external voltage riser is adopted. The equipment adopts 320*240 large screen graphic LCD that has a clear display under hard light, and RS232 interface which can communicate with PC for test data upload. Convenient operation of equipment with rotating mouse.
