DVA-402D CTPT Analyzer
DVA-402D CT/PT Analyzer
Application:
Transformer comprehensive characteristic tester is a automatic CT, PT characteristic tester. Test including CT volt ampere characteristic test, PT volt ampere characteristic test, CT ratio and polarity. It is a special test device for relay protection and high voltage isolation of current transformer test and voltage transformer test.
Features:
◆Supports detection of CT and PT
◆Meet the requirements of GB1207, GB1208 and other regulations.
◆All testing items can be completed on a single machine without external auxiliary equipment.
◆With fast micro printer, you can print test results directly on site.
◆Adopt intelligent controller, simple operation.
◆Large LCD screen, graphical display interface.
◆Automatically give CT/PT (excitation) inflection point value according to the procedure.
◆Automatically give 5% and 10% error curves.
◆Can save 3000 groups of test data, no loss after power down.
◆Support U disk transfer data, can be read through the standard PC, and generate WORD report.
◆Small and lightweight ≤22Kg, very convenient for field testing.
