DESIGN WIRE CONNECTION GROUP INSPECTION EQUIPMENT OF THREE PHASE TRANSFORMERS BASED ON TWO VOLTMETER METHOD AND DATA PROCESSING USING NEURAL NETWORK

Abstract

The identification of the wire connection group of three-phase transformers(WCGTT)  is an important step in the entire process of inspection, testing transformers. This is particularly important for the coupling transformers when they are working in parallel or we consider the phase angle of the supply voltage for the control circuit. However, nowadays, mostly in the central laboratory of the electricity corporations are conducting structure determined by the method of wiring craft, inaccurate, time consuming and require the high care technician. To overcome this drawback, this paper offers the design a wire connection group inspection equipment of three phase transformers based on two voltmeter method and data processing using neural network is designed. The results of testing this equipment show that, the equipment works reliably, exactly.
