EPCP-II CT/PT ANALYZER is mainly used for field testing of P class CT and PT. The test items mainly include excitation characteristic, transformation ratio, polarity, demagnetization, 5％ and 10％ error curves, secondary circuit check, withstand test of power frequency alternating current and secondary load. Adopt LCD, built-in printer supporting field printing; supporting to use USB flash disk to dump data, with simple and convenient operation.


Features
  • ◆ Support the detection of CT and PT, single machine output voltage 0-2500V, current 0-1000A.
  • ◆ All test items can be completed on a single machine without external auxiliary equipment.
  • ◆ Equipped with micro fast printer, it can print test results directly on site.
  • ◆ Adopt intelligent controller, easy to operate.
  • ◆ Large screen LCD, graphic display interface.
  • ◆ Give CT / Pt (excitation) inflection point value automatically according to regulations.
  • ◆ Automatically give 5% and 10% error curves.
  • ◆ 3000 sets of test data can be saved without loss after power failure.
  • ◆ Support u disk to transfer and store data, which can be read through standard PC, and generate test report.
  • ◆ Small and light ≤ 22kg, very convenient for field test.
