JYW6300 Transformer Short Circuit Impedance Tester
This instrument is mainly applicable to low voltage load impedance test of 35kV and above power main transformers (single phase or three phases) in ex-works routine tests, overhaul tests, pre-tests, and acceptance tests.
JYW6300 Transformer Short Circuit Impedance Tester adopts a three-phase 220V low voltage power supply, which applies the current to the main transformer's AB, BC, CA high voltage winding, synchronously collect data and convert the rated impedance percentage of LV side of transformer.
Function Introduction
●JYW6300 Transformer Short Circuit Impedance Tester can measure short circuit impedance, short circuit reactance and three phase impedance voltage of transformers.
●The interface adopts intelligent touch mode, which is simple and convenient to operate.
●JYW6300 Transformer Short Circuit Impedance Tester adopts single phase 220V low voltage power supply.
●The wiring is simple and convenient, and three-phase tests can be automatically completed by one connection and one start, showing the result directly.
●Test power can be internal power supply and external power supply: The internal power supply is the working power of the instrument, and the external power supply can be input by the voltage regulator.
●When the internal power is used, the instrument automatically controls the output voltage and current automatically, without any external auxiliary equipment.
●With power clock and date display, the instrument can store 50 sets of data, and the data will not be lost if the power is failure.
●With large touch screen, the data is clear and easy to read, thermal printer printing.
●RS485 communication interface and U disk storage interface.
●JYW6300 Transformer Short Circuit Impedance Tester has the protection function of mis-connection of high voltage and low voltage, and has the function of transformer short-circuit and inter-turns short circuit protection. It has the protection function of power supply mis-connection with AC380V.
