Product description The Transformer short-circuit impedance tester comes with an adjustable power output. Regardless of single-phase or three-phase transformers, only one connection is required, and the instrument can complete the measurement of all winding pairs. The test and connection are simple. Main technical indicators and conditions of use Measurement accuracy: voltage, current: 0.2 level Power: COS>0.1: 0.5 grade; COS 0.1: 1.0 grade Impedance: COS>0.1: 0.5 grade; COS 0.1: 1.0 grade Voltage measurement range: AC 3V300V Internal power output range: voltage 0~250V, current 0~10A Current measurement range: AC 0.2A 20A Working temperature: -10-50 Working humidity: 80% Working power supply: AC220V ±10-50Hz ±1Hz Dimensions: 360mm 220mm 150mm Weight of the instrument: 20Kg
