Overview

Current transformer volt-ampere characteristic tester Only need to set the test voltage, current and step, the device will boost and trace voltage current characteristic test curve automatically, save the cumbersome labor of manual pressure regulation, artificial record, tracing curves, and so. Quick, simple and convenient.

I can not only test CT/PT DC resistance, volt-ampere characteristics, ratio and polarity, 10% error curve, angle difference and ratio difference, but also test secondary load of transformer, CT current test and PT AC withstand voltage test.

CT ratio not only supports traditional current method but also voltage method, so it can meet the test of CT in casing CT and GIS.

Volt-ampere characteristic test single machine output voltage 0-2500V, current 0-20A, can meet most of the transformer volt-ampere characteristic test.

220V single power input and avoids the risk of using 380V.

Overview

The digital three-phase shifter is a portable electrical tester composed of transformer phase shifter, digital phase display, voltage current digital display, output voltage adjustment, coarse adjustment, fine adjustment, and power supply, etc. The digital three-phase shifter combines the transformer phase phase technology with digital measurement techniques, which can be adjusted at any angle in the range of 0 to 360 , which has high precision, reading. Accurate intuitive, the voltage output is adjustable, the digital three-phase shifter structural components use independent fixtures, firm and reliable, full seals, easy to carry in the field and on-site use.
