Using current bridge of transformation ratio to measure transformation ratio is an old and tedious method. Because its measurable scope narrow, this method has been not fit for demand of modern Test technique, rapid and efficient. So our company manufactures the new full-automatic instrument that measures transformation ratio, adopting the modern electronic technique. It is small, light, precise, reliable and friendly. It uses big screen to show words and uses menu to operate. The group of transformation ratio can be measured just one time.
Our instrument is the ideal test instrument of the electric power industry department.
Main function and character
1）Automatically measure transformer connection group.
2）Automatically proceed transformation of group.
3）Automatically change phase sequence.
4）Automatically change scope of measurement.
5) Automatically check.
6) Aafter input standard transformation ratio, calculate relative error automatically.
7) When the measurement is finished just one time, testing voltage is isolated automatically.
8) Locate datum, the result measured is saved automatically. The former datum can be looked into.
