(1) Good stability & reproducibility, in the 500KV power station field test, the values of resistive current beat only 1μA. As the extensive adoption of a variety of high precision, low temperature coefficient components, making the test data with excellent repeatability, which provides a good basis for vertical comparison of the historical data.
  (2) This instrument adopts a special anti-interference method, can effectively eliminate the interference of B relative A, C phase, successfully resolved the issues of A-phase resistive current is too large, and C phase is too small.
  (3) Adopt sophisticated mathematical models including Fourier algorithm, can eliminate the effects of harmonic waves on the test results.
  (4) Test items is complete, total leakage current, resistive current, capacitive current, phase angle, peak values of resistive current, peak values of total current, the third harmonic current, the fifth harmonic current, fundamental waves active power loss, harmonic waves active power loss all can be tested simultaneously .It is simple to operate and easy to carry.
