HZ-II Transformer Short Circuit Impedance Test
HZ-II transformer short circuit impedance test
Transformer Short circuit resistance Tester introduction:
Short circuit resistance is an important parameter of the transformer short-circuit impedance method is the traditional method for determining winding deformation, according 1094.5-2003 and 60076-5 : 2000 provides that the amount of change in the short-circuit reactance is an important basis to determine whether the transformer winding deformation
Transformer Short circuit resistance Tester Functions and Features
- Measurable transformer short-circuit impedance, transformer short-circuit impedance, impedance voltage three-phase;
- Can display voltage, current, power, frequency and other parameters of each test;
- Use only single-phase 220V AC power to complete the measurement, in the absence of an AC power source, you can use small power UPS power supply (500VA line can);
- Test power selectable internal and external power supply: internal power supply that instrumentation, external power input by the regulator;
- Wiring is simple and convenient operation, a wiring, a three-phase measurement can be done automatically start directly display the measurement results;
- When using the internal power supply internal automatic control of output voltage and output current, without any auxiliary equipment
- Automatic frequency correction to eliminate errors caused by the frequency fluctuation;
- Store thousands of measurements, the instrument does not power down memory built-in, measurement data can be stored for a long;
