Product Introduction

This product is specially used for measuring the capacity of distribution power transformer, measuring the no-load and short-circuit loss of transformer, and has the function of harmonic analysis, which is convenient for analyzing the quality of on-site power network. The device can automatically check whether the wiring is correct and display the vector diagram of the three-phase current and voltage when testing the three-phase transformer. At the same time, necessary correction (such as waveform correction, temperature correction, unrated voltage correction, calibration, unrated current correction) is introduced to make the test results more accurate.

Product names:Transformer capacity test instrument , transformer capacity load tester
