Winding Deformation Diagnosing Short Circuit Impedance Test Of Power Transformer
Product Description
I.introduction:
Transformer LV Short-circuit Impedance Tester applies to LV load impedance test during delivery, overhaul, trial test and handover test of power transformers (single phase or three-phase).
It tests the short-circuit impedance (%) of power voltage on site and compares it with the value indicated on the nameplate or the factory default to find out any defects including but not limited to winding displacement or deformation due to currents from major failure during transformation, installation or operation following the delivery test. (The short circuit change shall be considered as significant if it exceeds ± 3% as specified in China International Conference on Electricity Distribution 2000 ("CICED 2000")).
II.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;
