Three phase transformer Turns Ratio Meter TRM300 makes automatic measurements with no need to set any parameter and automatically completes 3 phase ratio and vector group measurement in just 3 seconds by pressing a single key, Basic Accuracy is 0.1%

Description

Three phase transformer Turns Ratio Meter TRM300 uses a programable source which can output singe phase two phase & 3phase sine wave output with adjustable output frequency.

Three phase transformer Turns Ratio Meter TRM300 makes automatic measurement with no need to set any parameter and automatically completes 3 phase ratio and vector group measurement in just 3 seconds by pressing single key

Built in 3 phase source can measure turns ratio of different connection group such as Y/y, Y/d, D/y, D/d.

For unknown vector group it can measure the vector group, polarity to clearly display first & second winding connection vector group.

It can also indicate on load tap changer position, first & secondary voltage oscillogram and phase relationship. As well as fist & second harmonics voltage to facilitate the analysis of transformer failure
