Product name: HCZK-II Transformer Short-circuit Impedance Tester
Category: Transformer Comprehensive Test Series
Detailed Introduction
Product Introduction
Short-circuit impedance is an important parameter of the transformer. The short-circuit impedance method is a traditional method for judging winding deformation. According to GB1094.5-2003 and IEC60076-5:2000, the change in short-circuit reactance is an important basis for judging whether the transformer winding is deformed.
功能特点
※ It can measure transformer short-circuit impedance, short-circuit reactance, and three-phase impedance voltage;
※ It can display the voltage, current, power, frequency and other parameters of each test;
※ It can complete the measurement only with a single-phase 220V AC power supply. In the absence of AC power supply,
※ It can use a low-power UPS power supply (online 500VA is sufficient);
※ The test power supply can choose internal power supply and external power supply: the internal power supply is the instrument working power supply,
※ The external power supply can be input by the voltage regulator;
※ The wiring operation is simple and convenient. After one wiring and one start, the three-phase measurement can be automatically completed, and the measurement results can be directly displayed;
※ When using the internal power supply, the output voltage and output current are automatically controlled internally without any external auxiliary equipment;
※ Automatic frequency correction can eliminate the error caused by frequency fluctuation;
※ It can store thousands of measurement results. This instrument has a built-in non-power-off memory to store measurement data for a long time
