ZSBKC Transformer On-load Tap Changer Tester
Overview
ZSBKC Transformer OLTC Tester is used for measurement and analysis of the OLTC index of power transformers and special transformers in power system. It is a integrated electrical measuring instrument controlled by computer, can measure the transition time, the transition waveform, the transition resistance, three-phase synchronicity and other parameters through a specially designed measuring circuit. Users may measure by connect the instrument with the tap-controller or connect with the transformer's three-phase casing and the neutral point.
Main properties
The instrument has functions of data analysis, storage and printing. It updated the power transformer OLTC measurement methods and provided a specific testing way for OLTC testing, greatly improved the power system operation security with its accurate diagnosing of the potential OLTC failures in equipment preventive tests and in transformer repair.
