Product Description
It is designed for analyzing current transformers and voltage transformers of protection or measurement use. Which is suitable for laboratory and on-site test.
Features
Test stable and instant parameter of CT/PT(protection type, measurement type, TP type).
Exciting voltage up to 30kV.
Finish all testing subject by itself, no need to connect auxiliary equipment.
Built-in printer, to print results easily.
Large screen LCD, graphically display.
Auto display excitation inflexion point value, 5% and 10% error curve.
Save 3000 groups data.
With USB port. The data can be saved in USB disk and read by PC.
Portable design, suitable for on-site test.
Working condition
Input voltage: 220VAC± 10%, rated frequency: 50/60Hz (range: 45-65Hz)
The quality of input power supply may influence testing result of CT/PT analyzer.
The analyzer should be supplied by power supply socket which have ground protection. If ground protection connection is not good or power supply is not isolation connection with ground, the analyzer can still work but we could not promise the security.
Environmental temperature is 23 degree± 5 degree.
The assured value is valid within one year after factory calibration.
