SLB-II Fully Automatic Ratio Tester

according toAccording to IEC and relevant national standards, transformer ratio testing is a necessary item in the production, user handover, and maintenance testing of power transformers. This can effectively supervise the quality of transformer products during production and use, prevent inter turn short circuits, open circuits, connection errors, internal faults or contact faults of the voltage regulating switch.

Our company's multifunctional portable fully automatic transformer ratio tester is designed to meet the on-site usage requirements of users. It is easy to operate, has complete functions, and stable and reliable data. In addition, it can also be used for blind testing (accurate measurement of transformer ratio and group number without knowing any nameplate parameters of the tested transformer); Can adapt to the needs of variable ratio testing for various large, medium, and small transformers.

The instrument adopts a large screen true color LCD as the display, with a fully Chinese graphical operation interface and a LCD display interface with Chinese character prompt information and multi parameter display. The human-machine dialogue interface is friendly. The instrument is equipped with a large capacity built-in power failure memory that does not lose data, and can save on-site verification data.
