Open-circuit voltage tester is a special instrument used for testing open-circuit voltage peak of current transformer, the technical indexes comply with regulations in IEC185:1987 and national standard GB1208:1997.
The instrument has many advantages, such as wide measurement range, automatic range switching, digital display, high input impedance, high accuracy, stable and reliable performance, light structure, beautiful appearance, simple operation, etc., which has gained wide trust and good reputation from massive users. Besides current transformer factory test, the instrument can also be applied in situations where it is necessary for power transformer manufacturer and other power departments to measure voltage peak value.
The instrument does not only have advanced circuit design, but also have compact structure, beautiful and elegant appearance, strict production process, it focuses on quality and tracking management. Compared with similar domestic and overseas instruments, it has higher cost performance, being an ideal instrument for instrument transformer, power transformer and other power departments.
