I.Design Purpose
Designed for automatic testing of protective and metering CT/PT, suitable for both laboratory and field testing.
II.Reference Standards
GB 1207-2006, GB 1208-2006
III.Main Features
• Supports testing of CT and PT
• Meets the requirements of standards such as GB1207, GB1208, etc.
• No external auxiliary equipment needed; all test items can be completed with the single unit.
• Built-in micro fast printer, can directly print test results on site.
• Adopts intelligent controller, simple operation.
• Large screen LCD, graphical display interface.
• Automatically provides CT/PT (excitation) knee point values according to standards.
• Automatically provides 5% and 10% error curves.
• Can save 3000 sets of test data, not lost after power off.
• Supports U disk data transfer, can be read via standard PC and generate WORD reports.
• Small and lightweight ≤22Kg, very convenient for field testing.
